I am selling my Sinn 103 ST SA, which I purchased (from the original owner) in the past 3 months. I am selling it to fund other purchases, and thought it would be a lifetime keeper, so I hope it finds its forever home with you.

The condition of the watch is excellent, close to new. There are no significant marks or blemishes, the watch is truly in immaculate condition (clean crystals, bezel, etc.). The watch seems to keep chronometer-level time and I have not noticed any significant gain or loss of time.

You will only find micro swirlies on the polished links and clasp + a micro swirly on the left lug (almost impossible to catch with a camera). The watch was purchased originally from Watchbuys in February 2018 on a black Sinn leather strap (included). I purchased a brand-new Sinn metal bracelet (includes 3 unused links) and a Sinn vintage strap ($150 value) and I will include BOTH. You are getting the full kit. The watch comes with the original box (perfect condition) and papers + the Watchbuys warranty is good through February 2020 + Sinn Black Leather Strap + Brown Sinn Leather Vintage Strap.

If you know this watch, you know the total value of everything I am selling (well over $2600). Please read this clearly: I am not looking to trade so will not respond to trade offers, I also will not respond to low ball offers as this is a watch that will likely increase in resale value. Selling for a firm $2350 + free shipping in the United States only. I will accept Paypal and will ship to a verified address, and kindly ask that you use the friends/family option to save me Paypal fees.

Thanks! David in Los Angeles (happy to meet L.A buyers in-person).
