I had been eyeing out these night divers for a while and when I saw one of the rare 180.123s with the ETA movement, I couldn’t resist. These shared the same case and movement as the Tag/Spirotechnique version. Just got serviced and a new crystal from Justin at tagdiver1000.com and on its on its way home to me.
The 180.123’s are higher than the quartz versions but not too much. They’re just harder to find. There are many quartz models out there and the range for them is between $700-900 depending on size and condition (many models are 38mm). The automatic versions are between $1200-$1500 but it takes some patience to find one and even longer to find one where the dial is in good condition
