FS: Sinn 903 Navigator with EP 40

This is the Sinn Navigator 903 with the Excelsior Park 40 movement. The EP 40 was featured in many 70’s chronos especially Gallet, Sinn and Excelsior Park. I have seen a few Gallets and Excelsior Park but have only come across one Sinn.

We’re looking at a very sought after chronograph, and this watch is reputed for being one of the most accurate professional chronographs of the 20th century. As proof, this last one was marketed with the slogan that it was indeed like a real computer.

This awesome 43 mm watch is running beautifully and comes on a limited edition Sinn leather strap. It includes a Sinn travel case and some of the original papers. I’m looking to sell only to raise funds. There is a EP and Gallet version sold via Chrono24 and both are way north of $5500. Looking for $4500. Please contact me at if interested.
