Vintage 1978 Seiko 6306-7001 Serviced JDM Divers Watch Original
This is a great example of the iconic Seiko 6306-7001 diver, produced in September 1978 for the Japanese domestic market (JDM). A true vintage tool watch, it features the desirable Kanji/English day wheel, a hacking movement, and a quickset day and date function, all operating corectly.
The watch has just undergone a full professional service by us, including all new seals. It’s running very well, keeping time within approximately +10 seconds per day. The screw-down crown operates smoothly, and the bezel has a satisfying, positive click.
Condition:
This piece is in great overall condition, with original factory dial, hands and all original Lume. The case also maintains its original factory finish and has not been polished. While there are expected signs of wear consistent with age, there is no evidence of misuse.
It is currently fitted with a brand new Seiko flat vent dive strap for comfort and vintage authenticity. Original stiff strap inculded. Please note that while all new seals were installed during the service, the watch has not been pressure tested and is not guaranteed to be waterproof.

A Note on Vintage Watch Ownership
Vintage mechanical watches, while robust and reliable, are not as precise as modern quartz timepieces and may require periodic servicing. Some gentle wear and natural patina should be expected with an original watch of this age. Treated with care, it will continue to be enjoyed for many years to come.
At TEMPO PRIMA, we believe vintage watches should not be worn in water, regardless of their original specifications. We do not pressure-test vintage watches and therefore cannot guarantee water resistance. To preserve the longevity and integrity of these timepieces, we strongly recommend keeping them dry and avoiding any exposure to moisture.
