good watch

this replaced my Titan II from ST. Moritz. easy to read. choronograph is great. (i use it for smoking food, bike riding and any thing i need to time). i wish they would add the alarm back and go back to having all black hands, as the second hand is a little hard to read but the blue dot helps. i highly recommend.

Great Features, Legibility and Value!

I'm enjoying my Flatline for about a year now. SUPER legible! The thing hugs the wrist (mine 7 inches) and the chrono is immediately accessible without any fiddling around. Everything was well aligned. The all-brushed steel case says "I'm all business" yet this watch is a strap monster and looks good no matter the color or type of strap you want. I have a blue stingray that is the jam. I have the white face model and the entire face is lumed. This is a keeper in my collection. Recommended without reservation!


An impressive watch

The Flatline Chrono (white face) is my second Momentum, my first an Atlas I picked up 15 years ago and is still going strong. First and foremost the images on this site do not do enough justice to just how beautiful this watch is. The Flatline is an impressive watch from the get go. The fit and finish is amazing and when you get up close the styling details really pop. This Chrono has some heft to it but not so you’d notice it once on your wrist. The SS bracelet is flawless and comes with enough links to easily get the fit just right. The flush fit sapphire crystal does its job allowing you to see the easily readable dial face. The Chrono works perfectly and all hands realign exactly after reset. Since wearing the Flatline I have seen no shift in time, spot on every day. You will not be disappointed with this time piece, it surpasses in style, functionality and overall quality to similar style watches twice the price if not more. One more thing about this watch that I love is it’s made in BC Canada.

keeping track of time

If you have watches, then one must be a chrono. The Flatline Chrono was my first Momentum watch. Because of it, there are now four others in the house; hey, if I like them that much, then my partner should have a couple, too. This was a tool watch to replace my old Rotary dive watch, which was too scratched, beat up, and too small (36mm) by current standards to deserve another battery. I've had the Flatline Chrono for years. (It can tell me exactly how long I've been putting off posting this review.) It was the watch worn to the boat, cycling, working in the yard, and on ski patrol. It still looks new. Seriously. New. Unlike most chronos, this one has an easy to read pilot style face. Big enough to use with a design that works and looks good even when not wearing a T-shirt. The case is very nicely finished and the SS bracelet is a quality complement. Pushers are nicely weighted and easy to use. The dials are very entertaining when resetting the timer. Highly recommended.

Dear Tim, Thank you again for the kind words, we really appreciate you taking the time to write these reviews :) All the best, Team Momentum

I just received my Flatline Chrono 42 with a rubber strap and couldn’t be happier. The watch has a large dial but not too big for my small wrist. It is light weight and very comfortable, especially when compared to my other watches. The dial is clear/easy to read. It does NOT have the cluttered appearance that you get with most chronos. The numbers and hands glow in the dark well enough that I could still see the time when I woke up at 0345 this morning. I will say, however, that I’ve owned watches from St-Moritz Watch Corp. in the past that have lasted 20 yrs. They seem to make a solid product for a decent price; and I hope this watch will last just as long.
