WM Watch WM212 Review – Solid Diver Watch Specs

The sea has always demanded respect — vast, unpredictable, and indifferent to human endurance. The WM Watch WM212 captures that spirit perfectly. It’s a diver’s watch built not merely for aesthetics, but for the practical business of exploration. With its Seiko NH35A automatic movement, screw-down crown, sapphire crystal, and 100 m water resistance, this piece blends reliability with visual character. Retailing for just over $100, the WM Watch WM212 stands as a confident, thoughtfully engineered tool watch with more refinement than its price would suggest.

Design & Case

The 41 mm diameter case strikes an ideal balance between stance and comfort. At 12.2 mm in height and 47 mm lug-to-lug, the proportions make it wearable across wrist sizes, aided by downward-facing lugs that prevent overhang. At 160 g, it feels substantial yet well balanced.
From the side, horizontally brushed flanks create a structured look, offset by polished lug hoods for contrast. Beveled transitions soften the geometry, while the clean split between brushed and polished surfaces gives the case a premium feel. On the right, a 6 mm screw-down crown — signed with the WM logo — operates smoothly and threads confidently, sealing the 100 m water resistance.

Flip the watch over and you’ll find a stainless-steel exhibition caseback with a mineral crystal window, engraved around the perimeter to denote the automatic movement, steel build, and depth rating. It’s not decorative, but it’s honest and functional — showcasing the Seiko workhorse within.

Movement & Crown

Powering the WM212 is the Seiko NH35A automatic caliber. It runs at 21,600 beats per hour (six ticks per second), with a 41-hour power reserve, hacking, and hand-winding capability. It’s undecorated but dependable — a proven engine that makes servicing easy and accuracy stable.

The crown’s threading is fine and precise, neither loose nor gritty, and its moderate size makes it easy to grip. Together with the caseback, it supports the watch’s 100-meter rating — a true dive-ready spec in a watch of this cost.

Bezel

The 120-click unidirectional bezel is a highlight. Each click feels crisp, heavy, and positive, rivaling the tactile precision of far more expensive models. There’s virtually no back-play, and rotation resistance sits comfortably between firm and smooth — “Seestern or San Martin level,” as the transcript put it.

The polished navy-blue ceramic insert features a luminescent triangle at 12 o’clock instead of a simple pip, adding a modern accent. The deep coin-edge grip makes it effortless to turn even with gloves. Overall, it’s one of the most refined bezels found at this price point.

Bracelet

WM pairs the 212 with a beads-of-rice style bracelet, mixing polished inner beads and brushed outer links. It’s a daring choice — slightly dressier than a traditional tool bracelet — but it works here, balancing the watch’s rugged nature with sophistication.
The male inverted end links keep the effective lug-to-lug compact at 47 mm. Each link measures 8 mm, improving articulation and wrist drape.

The bracelet feels solid and fluid, not tinny. The signed clasp offers six micro-adjustments, double pushers, and a milled inner wing — a genuine upgrade in this segment. The result is a bracelet that’s both functional and unexpectedly comfortable.

Crystal & Dial

The WM212’s personality lives in its dial. Its crystal-like texture mimics frost on glass, fading from white at the center to deep blue at the edges — an effect reminiscent of looking into clear ocean depths. The brushed rehaut carries a printed minute track, reinforcing the dial’s sense of depth.

Applied indices are chrome-edged and filled with lume, maintaining symmetry with the Arabic numerals at 6, 9, and 12. The baton hands follow the same polished styling, while a framed beveled date window at 3 o’clock adds utility without clutter. Branding remains restrained: the WM logo below 12, and “Automatic” plus “100 m” above 6.

A flat synthetic sapphire crystal with anti-reflective coating caps it all, sitting flush with the bezel for a clean, seamless look. It resists scratches effectively and keeps reflections low. The result is a dial that feels both rugged and luxurious, with surprising visual depth for a $100 diver.

Summary

The WM212 proves that even within the crowded budget-diver segment, there’s room for nuance. Between its sapphire crystal, ceramic bezel, and the tactile satisfaction of a perfectly damped rotation, this watch over-delivers in nearly every respect. The frosted-gradient dial distinguishes it from the usual homages, giving it genuine identity. Minor trade-offs — such as the mineral caseback window — are easy to forgive when the overall execution is this convincing. For a little over a hundred dollars, this is not just a capable desk diver — it’s a versatile, confidently built companion ready for sea or city alike.
