These have become impossible to find - especially in this condition.

The watch is in excellent condition, and hardly shows any sings of wear.

I am including an extra Sinn rubber strap to go along with the tegimented bracelet it originally came with.

Asking $3750. Open to trades for Omega, Tudor, other Sinn, Grand Seiko, or would be willing to trade up for a Rolex of some sort.
