Another Momentum Watch for my collection
The Flatline Chrono has become my daily "go to" watch. Stylish, perfect size, easy to read....and I get many compliments. I paired this watch with a yellow Nappa leather band to make it unique. The quality of Momentum watches and client care have made me a loyal customer.

Flatline Chrono [42mm]. Bought one, then bought another.
I bought one of the black-faced watches with the black strap and was so impressed by the look, fit and time-keeping that after a short while I bought another. This time the white-faced version on a brown cloud leather strap. I guess that shows what I think of them. Do yourself a favour and buy one (or more), while you still can.

Love this Company
I have had a number of timepieces over the years mod to high priced. My Momentum Atlas is 20+ year in use and the only one hanging in there. I decided to get the Slimline Whir full lume chronograph for a an addition to the Atlas as it’s here to stay Me?… I love the chronograph. The movement is clean in graphics, super accurate and comfortable too for a larger watch. This is a very consumer supportive caring Co. with sincere pride in every aspect of aesthetics & functional design offered at a great price! Nice to work with - very pleased with my new purchase (and my old one too.)

Excellent watch for the money spent
All of my momentum watches have always been a joy to own and wear, and this one is no exception.

A white watch face hits different.
I had to return the first one - the crown just kept on unscrewing and falling off. But customer service was fantastic - suggested a straight exchange rather than warranty service and everything was taken care of w/o issue. The pillbox case is beautiful - rising straight to the bezel and curving over with almost no transition, maybe one of the best cases Momentum makes. It wears smaller than it is with the curved lugs. The white face makes it look dressier, and the cloud leather band is extremely comfortable. A very legible face and understated chrono dials pair well with a suit or a tracksuit. I own a few Momentum watches now. This is one of my least casual ones.
Thanks for your question. I would say our Flatline Chrono has our mid-grade lume. It is not Super-LumiNova, but glows well for some time. Hope this helps.
