I am putting up for sale my beloved and rare Sinn 903 Navigation Chronograph. For those that don’t know, after Breitling faced financial difficulties in the 1970s due to the quartz crisis, Helmut Sinn acquired the rights to the Navitimer design, leading to the creation of the Sinn 903. As such this is not an homage but, in my opinion, the true Navitimer as it’s retained the classic design and proportions. If anything, modern Breitlings are the homage IMO. Not only that but I think it has a number of improvements over the Breitling including a classic 41mm case size, screw down crown, and 100 meters of water resistance making this a perfect daily! I lusted after this watch for years and finally found the perfect example but my eye has now wandered again and I’m reluctantly putting it up for sale or trade (see below). Extra video: https://imgur.com/gallery/exYxMob This watch is in excellent condition. Crystal and case are clean. Due to the high polish on the bracelet the bracelet does have usual desk diving swirls and marks but nothing outside of casual wear you would expect to see. It was serviced recently in 2018 by RGM the famed watchmakers and official service center in the USA for Sinn. The watch runs great and keeps time within spec by my casual observation. It comes with the original inner and outer box, manual, warranty card, Sinn tool, and receipt for the service by RGM. The watch is currently sized for my 7in wrist and comes with 2 extra links. Price: Recent eBay sales are between $3k-$3.3k on bracelet for this rare bird not including taxes you would have to pay. I’m asking $2,600 shipped and insured in CONUS. I will accept Zelle only for this one no PayPal or Venmo due to scams. I’m only selling to buy a Speedmaster Professional. So no trades except I will only accept trade offers for a Speedy Pro (I can add cash as needed). I have a lot of transactions on here, hundreds on eBay, and hundreds on my own Etsy shop! Feel free to ping me for any references.
