M20 DSS Diver [42mm] - Black

10 reviews
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. The double-dome sapphire crystal adds an interesting “bubble” effect to the rounded case. At night, the SuperLuminova luminous markers and hands come to life.

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.

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.

Super watch

Hello everyone. I want to leave my review. I have been looking for a watch for every day for a very long time. Such that they are not afraid to get wet or scratched. When I saw this model, I immediately liked it. And I ordered them. After the payment was made, they were sent to me by DHL. But they were deployed on the border with Russia, since DHL does not deliver parcels from abroad to Russia to individuals. I got very upset. But the store managers did not leave me and sent them back to me by regular mail. For hours I am very satisfied. At first they seemed heavy to me, but over time I got used to it and do not take them off even at night. The backlight shines almost all night. I have not tested the water resistance yet, but you can go to the shower. Super watch.

Professional Quality 200m divewatch at an affordable price!

I needed a heavy duty 200m rated dive watch for both work and water activities. I soon discovered a multitude of inexpensive "200m" watches that, after reading the reviews, all turned out to be fake! Then I discovered the incredible Momentum Watch Company out of Vancouver, Canada and it was immediately obvious that this was the Real Deal! This small but innovative company takes great pride in every watch they make and uses only the best components available. They have a huge selection of watches but the M20 DSS Diver exactly suited my needs! This handsome watch is sturdy with a beautifully finished two-tone stainless steel band and offset screw down crown - a true professional watch with a real 200m depth rating! It looks and feels great on my wrist and is exactly what I was looking for! you can tell by the weight: this is truly well built! It was shipped to me direct from the factory and arrived, very carefully boxed and packed, in just 5 days. I could not be happier with my watch and this wonderful Company! Check out their new website - it is full of the most interesting and valuable information - a real and fun learning experience - and you can peruse their varied selection of every type of watch!
