I am embarrassed to say that I had forgotten that I even owned this watch until today. Someone on another forum was asking about a quartz central chrono watch and that triggered my memory. In case anyone else might be interested, here is a mini review of it:
It was part of the old Citizen Promaster Tough series and retailed for ~73,000 yen in the late 90's. Of significance is the fact that it can do two unique things:
1) Measure altitude. Interesting, but I rarely if ever have the need for that
2) More interesting to me is the fact that it has a central minute totalizer hand, which is quite rare in chronographs. Moreover, the watch is capable of timing up to 99 minutes this way!
Note that the chapter ring has both a time and altitude scale. It is in altitude mode in the photo.
Here it is chrono mode reset to zero
Here it is with 8 minutes elapsed.
I suspect that the movement is derived from the analog aqualand depth meters (or vice versa), which to the best of my knowledge only have a small 60 min chrono subdial at 12 o'clock.
Citizen does not use this movement anymore, however it is OEM'd by Momentum watches as the Momentum Topograph:
And finally, here's the PMT along with it's mountaineering competitors from Seiko:
