Zenith Diver Black Dial ref A3630 on Gay Frères Ladder Bracelet

On Hold

The dive watch that climbs the ladder…

This is an amazing and original example of an early 70s Zenith dive watch. The black dial is is great condition with the applied Zenith star and applied hour markers with lume stripe. The dial has a broad white second chapter ring that adds to the watches elegance. The hands are bold, especially the arrow minute hand – they give the watch a cool look that is very unique. The case is in very strong condition, with strong lugs and bezel edge. The bezel remains in outstanding condition with a little damage to the pearl.  The screw down case back features the Zenith star in sharp condition. The watch is fitted with its very rare original Ladder bracelet that was manufactured by Gay Frères and is stamped as such.Read all about Gay Frères here.
