Product description

This Promaster Altichron was developed for hikers and mountaineers. It can withstand extremely low temperatures, which is especially important on top of a mountain. You can read the correct altitude on this watch, even in the harshest conditions. Hands free for climbing. Citizen has subjected the Altichron watches to rigourous tests and proved that these watches continue to work well even at temperatures below -20 degrees Celsius.

This Citizen watch has a case made of titanium with a diameter of 50 mm and is fitted with a rubber band. Inside the case lies a Citizen movement and the watch features a Mineral crystal.

The watch is 20 ATM. This means the watch is suitable for diving. The watch comes with 2 Year Warranty.
