Take a long look at this vintage Nautilus bracelet from the 1960s. You won't likely see another soon.
This solid stainless steel bracelet was made to fit divers from JLC and Longines, with a ratcheting wetsuit extension in the clasp. This one has the correct 19mm curved end links for the famed LeCoultre Deep Sea Alarm. You'll find it in the brochure for the watch that JLC collectors hunt around the world.
The bracelet is 6.25 inches before expansion. It is in near mint condition.
A word about the clasp: It is unsigned. The inner clasp says only: Stainless Steel.
Experts differ, but I have seen LeCoultres made for the U.S. market with unsigned clasps, while European and other markets have the signed ones. You decide.
Either way, this is a bracelet that doesn't surface often.
