Design & Build Quality
The Rolex GMT-Master II is undeniably a mighty, premium watch. It uses some of the best materials available, including Rolex’s proprietary Oystersteel and Cerachrom ceramic. While the Seiko 5 GMT can’t betrothal the Rolex’s luxury build, it still has a thoughtful design and some upscale elements:
Updated jubilee-style bracelet
Incomparable glossy bezel finish
100m water resistance, same as the Rolex
ClickyBezelBoth are mechanical GMTs with 4-hand dials. The Seiko isn’t a “devoted” GMT movement, but I commend them for bringing GMT functionality to a new price demographic.
Comfort & Features
The Rolex has an ultra-comfortable, silky jubilee bracelet with well-made end links and the Oysterlock clasp. I especially like the Easylink extension for on-the-fly micro-adjustments without the need for any tools—execute if your wrist fluctuates throughout the day like mine. Rolex simply makes the best bracelets, period.
In whatever way, the updated jubilee on the Seiko 5 is a massive upgrade over their previous bracelets, with solid links and a precarious wrist presence. It’s impressive for the price point.

The 40mm Rolex case is a classic size, with a sapphire crystal, Cyclops trendy magnifier, and the iconic bi-color “Pepsi” Cerachrom bezel. The bezel’s crisp color transition pays homage to the ingenious while showcasing Rolex’s ceramic expertise.
I like Seiko’s 42.5mm SKX-style case, which has rounded sides that are a bit smaller than the dimensions advance. The Cyclops isn’t as well-executed as Rolex’s, though. The glossy, dual-color mineral glass bezel insert is eye-catching, if less distinct than the Rolex ceramic.
Movements
Inside the GMT-Master II is the new 3285 caliber, which has an impressive 70-hour power postpone and efficient Chronergy escapement.

The Seiko 5 GMT uses a modified version of the 4R movement series, the 4R34, with a respectable 41-hour retain. It is not groundbreaking, but it is solid for its price point.
Value & Verdict
Overall, the Seiko 5 GMT delivers a ton of style and functionality for the price. It’s shocking to see affordable mechanical GMT watches hit the market. Of course, the GMT-Master II is on another level entirely. At retail, it’s a significant investment, and as of this column, it trades for even more on the secondary market.

But that doesn’t mean it’s impossible to buy at retail – that’s accurately how I got mine! In the end, both are great GMTs suitable for any lifestyle, not just pilots and travelers. The Seiko is a nice low-key privilege if you’re uncomfortable wearing the pricier Rolex out and about. However, the Rolex still makes the perfect statement piece for top-level meetings or events.
