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.

Pepsi GMT 20

I’m very happy with the Pepsi GMT 20!! Since I bought it, I’m only want to wear it. I also have an Aquamatic II and a Flatline Chrono Black. I love the blue red bezel. The size is perfect. I can’t wait to go scuba diving with it.

Beauty GMT

This is my second Momentum, and it won’t be my last. I like a nice quartz for it’s ease of use and just pick up and go. The finish on the watch is beautiful, with just enough shine to make it noticeable, it really does stand out. I have a 7.25 wrist and it sits beautifully as the rounded lugs hug the wrist and the bracelet feels solid and is very comfortable. I really have no negatives to talk about but just a note that one big improvement is the lume, Momentum has stepped it up and improved it a lot, great lume! Great communication by this company as well as quick shipping, and well packaged.

Absolutely amazing watch!

Holy cow this watch is blowing me away! Wow I am soooo impressed by this company I don't even know where to begin! The bracelet is one of the heaviest duty yet most comfortable bracelets I've ever found on a strap (yes hands down even better than any strapcode or Uncle Seiko strap). This watch comes in at 42mm but wears more like a 40mm due to the nice curved lugs. You get a 3 timezone GMT function since the inner chapter ring is also in a 24 hr layout. Sapphire crystal, 120 click uni-directional rotating bezel, Swiss Ronda Quartz Movement and amazing lume to top it off, make this one my new favorite "tool watch"! Oh and did I mention 200m wr! I was originally eyeing the new Timex Q GMT, but this hands down trump's that watch in the quality department!!
