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.

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.

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!

Better than I imagined

I just got the watch fitted today and I am very pleased with the detail of the finishing and overall quality of the watch. It feels like a steal getting a watch of this quality for the price that it is listed for. I am also very satisfied with how it sits on the wrist, it is very sleek compared to other dive watches and the styling of it is very versatile. Big fan!

Fantastic Watch

This watch is really great. The only reason I’m giving it 4 stars and not 5 is the metal band doesn’t fit my wrist very well. It is either too tight where it creates some discomfort or it is too loss where it slides everywhere. However I did purchase the leather bands and am happy with that. Also I would skip out on the tool for swapping the bands. I bent it on my first try and the other side doesn’t fit in the bands. The attention to detail is there for the actual watch. It came with the correct date and time which just goes to show the detail they put into the watch. Overall I’m very pleased with the watch but the accessories are a bit lacking in my opinion. Well worth the money though.

Very Classy!

I just received my M20 in the black dial configuration. It is reminiscent of the dial of the Rol%x Submariner with Momentum's own unique flourishes. This is a super classy design that can be worn dress up or dress down. I love how clean the face is. There are several nice finishing touches like the signed crown and momentum logo on the locking clasp. The hour markers are extremely visible with the right amount of height and have great Lume. I also love the lumed lollipop on the second hand as it makes it very easy to track. The second hand also hits center every hour mark! Bezel action is much better than my seiko-5 with little play, perfect resistance and great sound. I did have some trouble sizing the bracelet but that was my fault not Momentum's (hint go with a better quality pusher tool as my cheap Chinese one broke when pushing out a pin). The bracelet looks and feels great and is not a hair puller. I also purchased the Goma black rubber strap for use in the field/camping trips. The Goma rubber strap is excellent and compliments this watch incredibly well. Very comfy with strong vanilla smell. The bracelet is definitely more elegant but I want to keep it that way so the rubber strap makes a great compliment. Overall I am very pleased with this watch and look forward to using it at work, play and on extended canoe camping trips. I don't think the pics do this watch justice on how classy it is in person. The 42 mm is the perfect size for my 7.5" wrist.
