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.

M20 GMT [42MM]
The GMT Function

The M20 GMT features a precise, Swiss-Made quartz GMT movement — GMT time, or any second time zone, can be easily read, using the red GMT hand and the 24-hour scale around the outside edge of the dial. A third timezone can then be read by rotating the 24-hour bezel. The GMT complication was originally created for pilots who needed to track multiple time zones, but was quickly adopted by businesspeople and explorers alike.

Great Watch for a Great Price

Very well made bracelet and case. Looks great,is very accurate and slim. It just needs a magnifier like on the M50 to be perfect.

Beautiful but not without challenges

The watch is beautiful to look at. However, resizing the bracelet gave my local jeweler fits. Eventually, he worked through the issues and the watch now fits perfectly. I am a bit worried about the durability of the crown. It seems delicate and a bit imprecise. I wish it had more definitive clicks going between positions. I still have trouble locating the position to adjust the GMT hand. It would be more of a concern if I was a frequent traveler and had to reset it often. As it is, I've got it set where I want it and it will likely stay there a while. Overall, I am still very satisfied with the watch and it's getting plenty of wrist time. :)

Pretty good

I find the bracket clasp problematic. It will close but I must press extremely hard for the clasp to lock. I can engage the secondary lock but if I open the lock the bracket flops open. The watch is great though.


Momentum Watch

Hello Robert. Thanks for your comments. The clasp on the M20 bracelet has a "trigger-release", so it should open and close easily when you press the two trigger buttons on either side of the clasp. It can be closed by pressure only, but is much easier to close when you press the release buttons. The diver's safety lock is just for added security. If your clasp is not working as it should, please let us know and we will put this right for you.
