For your consideration is a May 1979 6306-7001 Third Diver. An extremely desirable Seiko diver’s watch that will be the best one in your collection. All components are completely original to the watch. The crystal is replacement hardlex from Klein.
The watch is completely original unto itself and I would rate the cosmetic condition as mint. The case has all of the original surface brushing on the upper surface and has not been polished; retaining all of its original case lines. There is one minor imperfection on the caseback. The dial and hands are in excellent condition and retain their original luminous material. The insert is incredibly well preserved and the case back tsunami still has the original brushing. The watch comes with an Uncle Seiko GL881 band.
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 250-270 range and the rate is (+/-) 2 sec/day. The case back and crown all have new, and factory correct seals. The crown was mechanically rebuilt to replace the gasket. 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.
