1938 Eterna Jumbo Clamshell / Triple Signed


Authenticity Guaranteed / 14-days Inspection Period / 1-year Warranty

Delivery: ca.10 days

Rare and highly collectable chronograph by Eterna. It features amazing oversize "Clamshell" waterproof case of a very special design patented in the mid-30s by Schmitz Freres SA. This case has 4 small screws behind the lugs to compress two parts of the case. Various Swiss manufacturers used this design for their chronographs in various sizes from 30 to 38 mm.

This particular piece is notable for the biggest possible "clamshell" case which measures 38 mm, extremely attractive sector/snail dial showing beautiful patina perfectly matching purple hands, and a reliable Valjoux 22-based movement. It is triple signed (case, movement, dial) and freshly serviced. A true gem for a true collector!

The watch went through complete service. Technical warranty: 1 year.
