One of the coolest Speedmaster variants in my opinion. Ref 3520.53. It is also known as the Ben Clymer or Shumacker Speedmaster. This watch is featured in A Man and His Watch as the watch behind Ben Clymer's interest in watches. I purchased this from a Japanese online store. It arrived running 45 sec slow per day with a chrono hand that was slightly off. I just had it serviced ($875 value) by a local professional and it is running great and about +9/10 sec per day. He replaced a gear, the mainspring, all of the gaskets, and did a full service. It comes watch only. I have the receipt from the watch shop and from eLady where I purchased it. It is sized for my 6 3/4 wrist and I have one extra link. The watch is dated to 1996. It has a tritium dial, but luminova hands. I think some transition watches may have come that way, or it may have been serviced some time ago. There is wear and some dings on the bezel and insert, but I think it looks amazing. The dial is in excellent condition. The watch is 39mm with a 44 hour power reserve. Asking $3500 shipped. Venmo, zelle, or PayPal depending on history. References available for interested buyers. Thanks! The only trade I would be interested in is for the big box 1861 Speedmaster Professional 311.30.42.30.01.005 plus cash depending on condition.
