Job Complete – SEIKO 7005-8030 – This Watch Was Actually In Vietnam

By Uncategorized

The SEIKO 7005-8030 is confirmed as an issued watch to special forces during the Vietnam War. The owner of this piece tells me the watch was actually in Vietnam and was not a civilian purchase later on.

This piece dates to 1970 and was in very good condition. I ended up servicing the watch, replacing the seals, crystal and some parts inside that were damaged due to water intrusion. It’s now running great and ready for a few decades more service!

Another fantastic result. This watch was damaged by a past water intrusion. The minute track dial print was damaged and unrecoverable. Fortunately the luminous paint was in good condition and didn’t require replacement. To complete the job, a set of aftermarket hands was added, a new glass and new seals.
Inside the watch, the movement was upgraded with a 6119 top train plate and escape wheel along with the barrel arbor jewel upgrade. This brings the jewel count to 22 jewels. The setting on the escape wheel now has a “DIAFIX” setting on one side which will help with consistent timekeeping and better resistance to shocks.
After “re-packing” the crown with a new VITON seal, and a fresh set of seals elsewhere, the watch passed a 100m pressure test.

The service on this watch went like a dream. Already in excellent condition it only needed a full service, new seals and a new crystal. In this case, the customer decided to add my new urethane GL-831 substitute strap, restoring the watch to the original look.

After service & cleaning, the watch passed the standard 100m pressure test.

Despite these watches being called the “Doctor Chrono”, the pulsations scale is useless for measuring someone’s pulse. It’s likely the scale was more useful for timing radio signal pulses or something but nobody knows for sure the intent of the scale.

This watch was serviced, new crystal fitted and the hands coloured to the correct “tomato red” colour.

July 2019 Update – New Workshop and Address

By Uncategorized

Geday Everyone!

I’ve just moved to a new workshop and a new address. The fairly convoluted move and longer than expected move process really put a dent in my updates.

My new adddress is –

PO BOX 245
SA 5158

And the next lot of completed jobs are a bunch of SEIKO 4S15 “Alpinist” watches. All were serviced, cleaned and had the seals replaced. All tested a PASS on the pressure tester at 100M. The 4S15 movement is a modern respin of the 5256 movement from the 1970’s and regarded as one of SEIKO’s best movements.
