Garbage

The crystal is made of very soft glass, and I accidentally scratched both it and the bezel with a zipper shortly after receiving it (I was given it as a gift). I sent it in for service, and a full 3 MONTHS later, they finally sent it back to me from their depot, unrepaired, and have refused to give me a refund. The altitude measurement is also wildly inaccurate, to the tune of a few hundred feet of error.

The band is too fragile

It is the second one that I buy and I only use it occasionally and they have broken very easily. You can recommend another one of better quality

Excellent altichron citizen watch

I like this watch for its altitude reading, the lume in the dark, the compass with the click-free bidirectional rotating bezel, and its oxygen sensor. A good choice from the Citizen Promaster.

Promaster Altichron

First time customer. Very well built and good quality. Hardened storage case is a nice feature. Ordering was pretty straightforward, and the shipping was fast!
