Black 1675 insert with gold digits. Pretty sure this is NOS, although it didn’t come in its original sealed packing so can’t be 100% sure. Either way the condition is fantastic, and this is an original insert rather than a later service insert. Outer diameter 37.75mm, inner diameter 30.30mm.

Cost:
400 euros

Shipping:
Shipping will be added at cost price, which of course depends on destination country.

Shipping Country:
The insert will ship out of Germany

Payment:
Bank transfer or Paypal. I am going to be strict that Paypal payments should be friends and family as otherwise fraudulent reversals are too easy, and also Paypal will only be available to long standing members with positive trading history. Very "safe" buyers may also choose to use standard Paypal if they wish, but the fees haven't been factored into the price so for standard payments 4% must be added to the total.
