Up for grabs is a very rare 90’s Hydro Challenger good for 111000m These were made in the early days of Bell & Ross when Sinn used to make watches for them. What makes these so unique is the depth rating being made possible by the oil filled case which in addition to the depth rating also gives it an insane viewing angle which I tried to capture in the pics, almost looks like dial is the crystal. This particular example just came back from a full service which included oil fill and battery replacement (wont need another one till approximately 7 years). This one also has the seconds hand hitting the markers very accurately which is not always the case with these models. Case and bracelet were refinished during service but this is not a new watch so does show some marks. Bracelet will fit up to a 7” wrist ​ **No box or paperwork included** ​ **Price: $2999** or willing to trade for a cartier santos + plus payment Case 39mm Lug to lug 40mm Lug width 20mm Thickness 12mm
