Description

For your consideration is a December 1974 6138-3002 “Jumbo” Automatic Chronograph — An all original watch including the dial, hands, case, bracelet. The crystal is a new replacement.

Condition

The watch is completely original unto itself and I would rate the cosmetic condition as excellent. The case has not been polished and shows age and wear commensurate with a 48 year old watch. The dial is original to the watch and has a date stamp 4N, one month prior the case date (4D — see images). The dial is the most amazing and flawless black (not petrol). The chapter ring and hands retain their original luminous material. The hands reset exactly to their vertical positions. Bracelet is an original Seiko oval link and is full length. The crystal is a new replacement.

Case Dimensions

Diameter: 45mm
Width (L-to-L): 45mm
Lug Size: 19mm

The case back, pushers and crown all have new, and factory correct seals.
