Description


For your consideration is a September 1968 6106-8100 “Proof-Proof” Sport Diver Automatic Wristwatch. A very desirable and very early watch that has a rare seven digit serial number.

History of the Watch

This 6106 is part of my personal collection of watches. I do not know the origin before my ownership.

Condition

The watch presents as very original unto itself and I would rate the cosmetic condition as a 9/10. The case appears has nearly all the original surface brushing on the upper surface and has not been polished; retaining all of its original case lines.The hands are in extremely good condition. The dial and hands have been relumed. The watch comes on a vintage Speidel flat-vent band as shown in the images.

Service and Warranty

I serviced this watch on 07/30/2021. That process includes a full cleaning and evaluation of all movement components and proper lubrication. Lubricants used were Moebius synthetic varieties appropriate for this watch movement type. The movement has two custom produced, American made jewels in the ports of the barrel arbor. The amplitude of the balance wheel is 240-250 range and the rate is (+/-) 2 sec/day. The case back and crown all have new, and factory correct seals. This watch comes with a 100% money back promise of originality and a 1-year limited warranty on the movement from the time of sale.

Shipping through USPS 2-day. Non-US buyers — I ship with a flat rate using USPS International priority.
