Slim Case Design
While officially the M20 comes in at 42mm in diameter, the case shape makes the watch feel much smaller. Don't let its good looks deceive you: the M20 is durable and adventure-ready, with an off-set screw-down crown that won't bite your wrist and 200M-rating.

Great build quality.
What attracted me to this watch was, I wanted a no nonsense quartz diver that could go anywhere do anything. What I didn't want was an overbearing large hulking dive watch. the slim height makes it a perfect daily wear watch. The fit and finish punches above it's humble price tag with off the charts lume. What really did it for me was the double domed sapphire crystal, no regrets.

Great Watch.
This is a great watch. It is beautiful and tough like all Momentum watches. The lumen is incredibly good. Bought this watch while talking to Simon at Momentum. I have other watches but, this is my new WOW watch. Real glad I bought it. Thank you, Simon. Rob

Almost perfect
Great quality for the price. Bracelet, finishing, sapphire, the watch has it all. One small caveat that bugs me nonetheless - it could really use an AR coating, very hard to read in direct sunlight. I would not mind paying extra for this feature.
Customer service was a 10 out of 10
I was about to go on vacation and needed a new watch, I went to my local jewelry store in Osoyoos BC and was pleasantly surprised to find the M20. This watch is fantastic and I love its classic styling but above all the customer service and in depth information from the store sold me.


Solid everyday diver
I spent weeks (months?) looking around for a smaller diver under $300 and liked the design of the M20. What a lovely watch. I fitted it to my 6.5" wrist and it sits very well on it. Doesn't wiggle around, the dimensions of the face are just right, the case doesn't sit too high, the two-tone stainless strap doesn't pinch. My only complaint is the longevity of the lume, but it's never been an issue for me. I'm looking forward to trying more models from Momentum. Their customer service folks are very helpful and responsive. Kudos to y'all.
