A very nice, honest, all original example of this elegant, JDM-only chronograph, dating to November 1971. This reference was offered for only two years of production, and featured the 6138B 23 jewel movement. An excellent case with a clean caseback, and all with original factory finishes on all surfaces. Case measures 40 mm, less crown, and approx 44 mm from tip to tip on the lugs. Minor scuffs and scrapes appear, but reflect careful past use. Top bezel and crystal show some minor marks and scratches from use. The charcoal gray colored dial is in excellent condition with no visible blemishes. Both the radial brushing of the dial and the silver chapter ring catch the light nicely. Nice tritium lume at each index and on the hour and minute hands, and all appear in superb condition. Lovely silver Seiko Applied Metal Logo. The yellow tipped chronograph hand compliments the dial and stands out as an attractive element. The JDM-only 23 jewel 6138B movement is running very well, with good timekeeping. All Chronograph functions work correctly, and it resets to zero smartly. No known service history. Day wheel is in Both Kanji and English. This is an automatic movement with a hand winding option. Nice, unmarked screw heads in the movement are seen below The original Seiko Bracelet with XAB/321 endlinks is fitted, which is relatively unusual to find. The watch fits my 7 1/2" wrist well, with adjustment of +/- 5/16" either way without removing any links. No spare links available. This sale is part of a continuing reorganization of my collection. I’m building up a stash of “dry powder” for some anticipated future purchases. Price is $2750 USD, exclusive of any transactional costs, delivered to the USA. Paypal works well for me, and other methods can be discussed and mutually agreed to. Overseas shipment is also possible following a discussion and joint agreement. I accept returns only if the watch is mis-represented.
