In attempts to appeal to the “civilian” crowd, Blancpain produced a smaller line (34mm and 37mm) of dive watches under the “Bathyscape” moniker. A bathyscape is self-propelled deep-sea submarine, and Blancpain used this smaller-dive watch line to differentiate them from the Fifty Fathoms when sold in various retail shops directly to consumers.
This model, in the more desirable 37mm case, features a slate grey dial, a date function, and their trademark “bakelite” bezel. The example offered today is in mint condition, with only a little polish to the case. The dial is incredible, and all lume plots are still in tact. Also, the bakelite bezel, known to crack easily, is completely in tact.
