Description
Why it stands out:
– Clamshell case.
– Gilt dial with Breguet numerals.
– Telemetre and ‘snail’ tachymetre indication.
– Unpolished case and in well preserved condition.
What you should know:
– Light scuffs and scratches (nothing noteworthy).
– Spots to outer edge of dial due to contact with the waterproof casing (see pictures of dial taken out of case).
General information:
The “Clamshell” case, protected under Swiss patent No. 189190 (1936–37), was developed by Schmitz Frères and later licensed to Gallet. We find this number stamped on the inside of the case back. Outer case back bears its serial number along with some case and movement specifications.
Later strap and buckle, plexi crystal with some scratches.
