Omega Men’s 32630405004001 Speed Master Analog Display Automatic Self Wind Silver Watch review: precision chronograph for daily wear

Overview

This is a stainless steel automatic GMT watch with a 42mm case, a rotating bezel, and water resistance rated to 330 feet (as listed). In plain terms, it’s a mechanical, self-winding timepiece that can track a second time zone—ideal for travelers, remote workers, and anyone who wants the charm of a mechanical watch with genuinely useful functionality.

If you’re shopping for a versatile everyday piece that can pull double-duty for travel without venturing into ultra-luxury territory, this automatic GMT watch hits a practical sweet spot: tool-like capability, classic steel construction, and straightforward dimensions that will fit a wide spectrum of wrists. Quick verdict: a solid, no-nonsense automatic GMT watch that prioritizes function, durability, and daily wearability.

Because the listing keeps details lean, this review focuses on what’s verifiable: the case size (42mm), the automatic self-winding movement, the rotating bezel, the GMT functionality, and the 330-foot water resistance. Where the listing doesn’t specify (crystal type, thickness, bracelet, power reserve, lume, etc.), we call that out so you can buy with eyes wide open.

Design & Build

The backbone here is stainless steel. That matters more than it might sound: steel offers a proven balance of hardness, corrosion resistance, and everyday robustness. If you’re wearing your watch as a daily companion—commuting, traveling, working at a desk, grabbing coffee—steel endures, cleans up easily, and pairs with anything from a T-shirt and jeans to a sport coat.

At 42mm in diameter, this is a contemporary medium-large size. On most medium to larger wrists, it will have confident presence without drifting into oversized territory. On smaller wrists, 42mm can feel assertive; the final fit will be influenced by factors not listed in the description, such as lug-to-lug distance, case thickness, and the curve of the lugs. If the lugs are short and the case is well-contoured, 42mm can still wear comfortably and sit securely without overhang. Unfortunately, those details aren’t specified, so if you have a smaller wrist (say under ~6.5″), consider trying it on or measuring a similarly sized watch you already own.

The rotating bezel brings both function and personality. On GMT watches, bezels are often used to track additional time references or act as a timer. With an all-steel case and bezel system, durability is a highlight: metal bezels can stand up to knocks better than some insert materials. That said, the listing doesn’t specify the bezel insert (if any) or the detent system (e.g., 60-click, 120-click), so we can’t comment on tactile feedback.

Ergonomics and wearing comfort will depend on the bracelet/strap, clasp, and case thickness—none of which are listed. If it arrives on steel, expect a cohesive, classic look with maximum durability. If it comes on leather or rubber, comfort might improve and weight might decrease a bit. Swapping straps is a common upgrade path for many buyers, so if you want to fine-tune the style or comfort, you’ll likely have options.

Key Features

Automatic Self-Winding Movement

Why it matters: An automatic self-winding movement uses your wrist’s motion to wind the mainspring, storing energy that powers the watch. That means no daily battery worries and no cable charging. For mechanical watch enthusiasts, the appeal is tangible—a tiny engine ticking away on your wrist.

Real-life benefit: Wear it daily and it should stay powered without manual winding. If you rotate watches and it stops, a few turns of the crown and a little wrist time will bring it back to life. This kind of movement is valued for its craftsmanship and longevity; with basic care and periodic servicing over the years, a mechanical movement can be a lifetime companion.

Ownership tip: When you first receive the watch, give it a gentle manual wind (if the movement supports it) to prime the mainspring. Then set your local time and GMT hand (more on that below). If you won’t wear it every day, a watch box or winder can help keep it running—though a winder isn’t strictly necessary for mechanical health.

SEO note applied naturally: If you’re specifically shopping for a self-winding movement because you prefer a traditional mechanical feel, this model fits that bill.

GMT Functionality

Why it matters: A GMT watch allows you to track a second time zone at a glance, usually via a dedicated 24-hour hand and a 24-hour scale. Whether you’re coordinating with teams in another country, keeping an eye on home while traveling, or checking market open/close times, a GMT complication is practical.

Real-life benefit: Imagine your boss is in London and you’re in New York. Set the GMT hand to London time and keep local time on the main hands. Or you’re traveling from LA to Tokyo—set local time on arrival and let the GMT hand track your home base so you don’t call friends at 3 a.m.

How to set it (general guidance):

• Pull the crown to the time-setting position.
• Set the main hands to your local time.
• Adjust the GMT hand to the second time zone you need, typically using a 24-hour scale (on the dial or bezel).
• If the bezel carries 24-hour markings, you can also use the bezel to offset time zones without changing the GMT hand—helpful for quick mental math when schedules shift.

Note: The listing doesn’t specify whether the GMT is “caller” (independent GMT hand) or “traveler” style (independent local hour hand). The user experience differs slightly: traveler GMTs excel when changing local time; caller GMTs favor tracking multiple zones from a fixed location. Without specifics, expect a useful, straightforward GMT either way.

For SEO clarity: If you’ve been searching for an automatic GMT watch to simplify travel, this feature is the core reason to consider it.

Rotating Bezel

Why it matters: A rotating bezel adds practical timing and time-zone tracking flexibility. Some GMT bezels are marked in 24-hour increments; others in minutes for timing tasks. The listing states “rotating bezel,” but not its scale; still, both use cases are helpful.

Real-life benefit examples:

• Time a parking meter or steeping tea by aligning the bezel marker to the minute hand and reading elapsed time—no need to use your phone.
• Track a third time reference by setting the GMT hand to one zone and using the bezel offset to represent another. For instance, keep the GMT hand on UTC and rotate the bezel to see your client’s time quickly.

Best practice: Rotate the bezel gently and deliberately. If it’s unidirectional (not specified), you can only turn it one way—which is useful for safety in diving-style bezels. If it’s bidirectional (common for some GMT bezels), it’s quicker to set for time zones.

Secondary keyword included: rotating bezel.

Water Resistance to 330 Feet (Manufacturer/Listing)

Why it matters: The listing notes water resistance to 330 feet. In practical terms, that suggests everyday resilience—rain, hand washing, incidental splashes, and likely swimming in a pool.

Real-life benefit:

• Travel with confidence: airport security, quick showers (not recommended while wearing), and rainy commutes won’t be a worry.
• Pool or beach days should be fine as long as you follow standard water-resistance care basics.

Important caveats:

• Do not operate the crown under water. Always ensure the crown is fully pushed in (and screwed down, if applicable—not specified).
• Regularly check gaskets and seals during service if you want to maintain water resistance over time.
• Hot tubs and saunas can be rough on seals; avoid them while wearing any watch you want to keep sealed.

Secondary keyword included: water resistant to 330 feet.

42mm Case Size

Why it matters: Case diameter influences style, wrist presence, and readability. At 42mm, this watch provides legible proportions with a sporty stance.

Real-life benefit:

• Larger dial area typically means quick time checks at a glance.
• 42mm works well as a one-watch solution for many who prefer modern sizing—worn on steel, rubber, or leather depending on the occasion.

Fit guidance:

• Medium to large wrists (about 6.75″ and up) will likely find it comfortably proportioned.
• Smaller wrists can still pull off 42mm if the lug-to-lug is compact and the strap choice is tailored (e.g., a supple leather or curved rubber that hugs the wrist). Those measurements aren’t listed, so try it if you’re on the fence.

Secondary keyword included: 42mm watch.

Stainless Steel Construction

Why it matters: Stainless steel is the industry’s workhorse for a reason. It’s durable, relatively resistant to corrosion, and easy to maintain. It also pairs well with nearly any wardrobe.

Real-life benefit:

• If you bump a doorway or desk, steel can shrug off light contact.
• Cleaning is as simple as a microfiber cloth and mild soap and water for the case and bracelet (if applicable).

Care tip:

• Dry thoroughly after exposure to salt water or chlorinated pools.
• Hairline scratches can be expected over time on polished surfaces; many owners consider it honest wear. For a factory-fresh look, professional refinishing is an option down the road.

Performance & Use

Daily accuracy and reliability

• The listing doesn’t provide accuracy specs, movement caliber, or power reserve. Mechanical watch accuracy varies by movement and regulation, and what you experience depends on wearing habits and service history.
• Expect that consistency improves if you wear the watch for longer stretches (the movement stays fully wound). If you alternate watches, giving this one a quick wind before wearing can stabilize performance.

Setting the time and GMT

• Start with a full wind (if the movement supports it) to ensure ample power for precise setting.
• Set the local time first: align the minute hand to a known time signal for best accuracy.
• Set the GMT hand second: align to the second time zone you need (e.g., home, client, or UTC).
• If the bezel is 24-hour, you can offset it to read a third time at a glance. If it’s minute-marked, use it for timing.

Using the rotating bezel effectively

• For timing: line up the bezel’s zero marker with the minute hand; read elapsed time without doing mental math.
• For time zones: if the bezel has 24-hour markers (not specified), rotate it to reflect an offset from the GMT hand to get a third zone. If not, keep the bezel for timing and rely on the GMT hand for the second zone.

Water-resistance best practices

• Manufacturer/listing states 330 feet water resistance. That’s good for day-to-day exposure and swimming. Always ensure the crown is secure before contact with water.
• Avoid operating the crown or pushers (if any; not specified) when wet.
• Have seals checked during routine service, especially if you regularly swim with the watch.

Comfort and wear

• Size and weight are partially unknown due to unspecified bracelet/strap and thickness, but a 42mm steel case typically feels substantial yet manageable.
• If comfort is a priority, consider trying different strap materials: leather for dressy comfort, rubber for sport and water, nylon for lightweight breathability.

Maintenance and service

• Mechanical watches benefit from periodic servicing. The listing doesn’t specify intervals; many owners service mechanical watches every 3–7 years depending on use and environment.
• Keep it clean: rinse with fresh water after salt exposure, then dry thoroughly.
• Store crown-in and away from strong magnets; magnetization can affect timekeeping.

Practical ownership tips

• If you switch between multiple watches, keep a simple log of how the GMT is set (home vs. travel) so it’s quick to reconfigure before trips.
• If the watch stops, set it to an online atomic time reference to keep it in sync with your other devices.
• Consider a travel case if you plan to pack the watch in luggage; protecting the bezel and crown from knocks is always wise.

Pros vs. Cons

Who Should Buy This, and Who Shouldn’t

Who should buy:

• Travelers and frequent callers across time zones who want an automatic GMT watch to simplify scheduling.
• Professionals who prefer a classic mechanical timepiece with practical features over a smartwatch.
• Anyone seeking a durable, stainless steel daily watch that can handle commutes, office life, and weekends.
• Buyers who appreciate rotating bezels for timing daily tasks (parking, cooking) in addition to time-zone utility.

Who shouldn’t buy:

• Shoppers who need ultra-thin or very small watches (42mm could be large for wrists under ~6.5″).
• Divers who demand specialized dive features (e.g., ISO certification, helium escape valve); this is water resistant to 330 feet as listed, but not a pro dive tool.
• Users who want smartwatch functions (notifications, heart rate, GPS); this is purely mechanical.
• Buyers who need complete transparency on every spec (crystal material, movement caliber, bracelet type, etc.) before purchase; the listing is light on details.
