5 reviews
The M-Ocean is for those who prefer an understated design, in a more traditional, mid-size case. Big performance for a smaller wrist, with a 200M rated, matte-finish solid steel case and ultra-reliable, screw-down crown. The luminous dial/hands make it easy to read, day or night.

Better Than Diamonds!

Just received my 6th Momentum watch. Love beauty and function. I now have 3 of the colorful dive watch. . I am an Aquarian so….


Great marine construction watch.

I just bought a M Ocean from your shop and I couldn’t my be happier with it. The feel, strength and look is perfect. I work in marine construction and time and reliance on accurate time is crucial. I use the bezel daily to time work. The only thing possibly better than the watch was the staff at your shop. I’m not sure but you may be the last watch store in Vancouver and the guys that helped me pick the watch were awesome. I grew up in Fairview Slopes so it was a bonus to find such a great shop in my hood. You should have a photo section. I’d send you some pics of my new M Ocean on the derricks. -Marcus

Top Tier Field/Dive Watch

I bought this dive watch in May 2019 for my field work in the marine industry. Waterproof, with the sapphire crystal glass and slim 38mm case the watch has never failed me, it is reliable, rugged, yet elegant and in addition to trusting it in the field, I wear it for everyday use because the M-Ocean is multifaceted!

Dear Gibson, Thank you so much for the kind words, and we're thrilled you're enjoying your M-Ocean :) All the best, Team Momentum


An old friend

Just received my M-Ocean. It is anupdated version of the M1 which was a trusted watch of mine for years. Love the flieger dial. The size of this watch is spot on. I think there is a trend forwards more traditional sizes. The second hand on This example hits the indices very well. A big gripe of mine is a quartz watch that has a second-hand that misses the indices on the dial. The sapphire crystal is at coated and the fit and finish are very good. Most of all, I know this watch will be tough as nails and the customer service at St. Moritz is top notch.


Great traditional size

I really like this watch. It is an excellent fit on any average size wrist and in my opinion much nicer then some of the larger watches that have become bulky and overstated. It looks larger then some 38mm watches and it’s beautiful construction and readability are as expected from Momentum. This is one of my favourite go to everyday time pieces. Good value and good customer service. I own 3 Momentum time pieces.

Thanks for the review Pete!
