VINTAGE SEIKO 6309 7290 'O' DIVERS WATCH MOD AUTOMATIC DAY WATCH FULLY SERVICED

This classic scuba diver's watch has been professionally serviced and regulated, and is running beautifully, keeping accurate time. The dual-finish steel case has been expertly polished and rebrushed, and is in excellent condition. The watch also has 'Quickset' day and date display windows. The hands and dial markers have a luminous treatment.

Water resistance: While this watch will be perfect for every day wear we longer recommend diving as water ingress can occur.

Dial/Hands Seiko Dial, customised in the traditional 6309 Diver style, in a crisp white, in perfect condition.

Circular dial markers a stylised rectangle at 12, 9 and 6, all with an applied luminous finish. There are 'Quickset'  Day Date window at 3 o'clock.

 Minute markers run around the outer chapter ring, which is also new, colour matched to the dial, and set at an angle which adds an impression of extra depth to the watch head.

The hands are also new, in the classic 6309 Diver style, black-trimmed with a luminous fill. The luminous treatment on the hands and markers has been upgraded, they glow nicely after exposure to light, and while it won't shine all night, the effect lasts for a little while, a nice bonus on a refurbished or redialled watch, which often have little or no 'lume'.

Case The large dual-finish stainless steel case is in excellent condition, with minimal signs of use - in a satin-brushed finish to the upper surfaces, and a high-polish finish to the sides and back (I've had this expertly polished and rebrushed, and it has come up beautifully. I can't see any dings or obvious scratches, even up close, tiny 'hairline' marks if anything). The case edges remain crisp and nicely defined.

Bezel. Original unidirectional steel bezel, correct resistance, turns smoothly with 120 nicely ratcheted 'clicks'. It's in very good condition and has been fitted with a new bezel insert. It's designed in the 'Submariner' style, printed with elapsed-time markings in black.

Caseback The screwdown Caseback is in excellent condition, again expertly cleaned and gently polished, with only minimal  marks. The manufacturer wording on the caseback is clear and legible, see photo - plus the Seiko Wave logo in the centre.
 
Crown Original screwdown ridged-edge steel crown, offset at the 4 o'clock position, screws down and adjusts well. It's been cleaned and polished, and is in very good condition. The case tube and crown stem have been inspected, and are in good order.

Crystal New scratch-resistant Mineral Crystal, with no marks of any kind (checked under magnification).

Movement Seiko 6309 7290 17 Jewel Automatic movement. My watchmaker has fully serviced the movement for me, and replaced all the gaskets. He reports it is in excellent condition, and appears original to the watch.

Strap  Double flip lock solid stainless steel bracelet.
