The triumphant result of a long search

Gentlemen, I use an electronic translator. Sorry if something is badly translated. I got this watch recently. It was the last copy of the Flatline with a white dial in Russia. I looked at this watch for a long time, but decided to buy it only now - when they began to disappear from sale. And I bought both black and white! The watch is just the bomb! Very convenient size - 42X9. The highest quality workmanship. Great design. Thoughtfulness in the details. Good bracelet. And, most importantly, impeccable readability! A cursory glance is enough to instantly determine the time. This is probably the best watch I have ever owned. And there were many... Separately, I want to mention the excellent support. There were a couple of questions - an employee of the company immediately responded (unlike the Russian dealer) and for a long time and patiently told me everything that I asked. Thank you so much, Mr. Pennell!

First Impressions are Pleasing

I have been wearing the Flatline watch for only 25 days and here are the results so far: Rain, dust, dropping it on the floor, banging it around during a couple of construction projects, and brushing it against briars and tree limbs during jaunts into the woods have provided an adequate early test as to the Flatline's durability. The steel band still looks like new, the crystal is unscratched, and the time is still precise and correct. Upon arrival of my new watch, I set the time using an atomic clock as a reference. Twenty-five days later the watch shows a time that differs by about one second from that shown on the atomic clock. My only conclusion is, the atomic clock must now be off by one second. Long term durability of the watch remains to be seen but I am extremely optimistic. Based on the early results, however, I would highly recommend the Flatline watch to those who want a no nonsense, hard working, tough and accurate timepiece. And it looks nice on the wrist also.

Awesome all around watch!

Bought the Flatline 42 mm with black dial a few days ago. Already my favorite watch. For the money you get awesome specs that would normally cost much more; it feels more expensive than it is. The watch itself can be worn casually or can be dressed up. It has a super legible face, the sapphire crystal is extremely clear and its thickness and weight make it super comfortable to wear all day. The luminous dial works phenomenally well. All in all worth every penny and super happy with this purchase. Bill

Tough Stuff

I was looking for an everyday watch so I could give my Tag a break. I purchased the Flatline in 2017, immediately put it on (with a NATO strap) and went back to work on the renovation. That first day I was using a jackhammer not thinking that vibration might be a little hard on my new watch. Nothing I've done has phased this watch in the 21/2 years I've worn it, and with the Sahpphire crystal it's still looking great and running as accurately as the day I took it out of the box. Easy to read, clean looking, tough, and accurate. Very pleased.


Great watch

It started out bumpy, I took it to the lake the first day I had it for a 2 week vacation. The only problem? The face wasn’t waterproof, stopped working after less than 3 minutes in shallow water. Some time went by, and despite the watch being serviced numerous times issues persisted. I am, however, happy to announce that after some time the bezel was replaced under warranty. Now where I once dreaded going fishing, hiking or swimming, the watch has held up to torrential downpours, swimming/ snorkelling, and a quick plunge when pulling out the latest catch on the line. It took a while but I’m happy to say Momentum stands behind their warranty. They now have a happy customer.
