The Watch
.
Very Unusual Monnin Cased Bulova Accutron PVD Diver dating from 1980.
.
The Watch boasts a 38mm Blacked out PVD case that has one of the coolest and unusual dive features, a Depth Gauge built inside the Crystal.
.
This is an interesting watch, I've only seen a few other examples of this model.
We have had one with the same case before that was branded "Alpha" that sold almost instantly.

How the Depth Gauge Works
The Crystal is surrounded by a Capillary Tube, with a small inlet milled into the Specific Crystal at 3.
.
The inlet allows water into the channel as the diver descends into the deep. As pressure builds, the air in the channel is compressed and water pushes its way into the channel. The depth is read on the scale around the dial thanks to the separation between the air and water.
.
Pretty......damn.....cool

*Please note that this function has not been tested it is now a Vintage Timepiece, it has NOT been tested for Water Resistance and if you wish to Submerge this Watch, you will need to have the Watch Professionally Resealed before doing so!!*
