This is a Citizen Promaster Aquamount in stainless steel. The ultimate adventure watch, it is a diving and mountaineering computer, not to mention a great looking watch. Asking $425 obo shipping CONUS included. I purchased it new. It just doesn't get much wrist time anymore. It's in great shape and works like new. The band extends to be worn around a wetsuit. There are some scratches on the crystal I've tried my best to capture in the photos. Some minor scratching on the band from desk diving. I have all the extra links and the original boxes, warranty card and tag.
