I have noticed that this watch is not well known, not even to the forum members. Therefore, I have finally got my act together and made some pictures (and info) available to you. (The poor quality is due to the fact that the pictures have been reproduced from printed material, without a scanner.)

The watch model was also called Universal Timing Chronograph. I think the production of it has ceased.
Features:
The ability to shut the display off. For fancy dinners, I guess.
Automatic Light Control (ALC). Nothing new, as we know. Just the automated ability to adjust the backlighting intensity to follow the ambient light levels. (I have the impression it was possible to leave this backlight on, but that sounds terribly power hungry.)
The circuitry was developed by the same people in the Swedish defence industry that design electronics for anti-aircraft ammunition. This might give the watch good resistance to knocks and shocks.
PIN-number memory
Audible or silent regatta count-down alarm. When every hand in the crew have their own count-down going, there will be quite a racket on board
about at the time the gun will go off. This can be very distracting to the skipper.
Let me know if you encounter any technical difficulties with the pictures. It is the first time I make material public this way.
