Red Dead Restoration

This time I´m restoring a Citizen Promaster automatic.
It´s a japanese diving watch, waterproof up to 200 metres and powered by the citizen 8203A caliber.

The watch is in a bad condition: The stainless-steel-case is damaged, the glass is not original, glass and bezel are scratched and the movement is not running. As I try to wind-up the movement it winds-down immediately. Seems like an issue on the escapement-wheel.

A tooth and the pivot of the escapement-wheel is broken, i need to replace it. As well as the glass, the glass-gasket, the click-spring, the movement spacer and the bezel. After everything is cleaned, sanded and polished I can restore the brushed surface of the case and re-assemble the movement with some fresh oil. After that, this watch is in an awesome beat (+4 seconds per day) again.

Awesome, Luv watching these vids. One thing that’s mind boggling is that I never see anyone use a Torque wrench when putting a watch back together. After using several different types of Torque wrenches for the last 20 years on Jet Engines I just can’t fathom why they don’t use them on watches.

Citizen Promaster NY0040 - now upgraded with new movement​

The upgraded 8204 movement on this NY0040-17L is a welcome upgrade over the older 8000 series ancient workhorse.

I must admit that this design is another one of those hate-or-love thing.

Ultimately, this is a nice entry-level diver for those who don’t wish to spend too much on a practical watch.

Watch was on loan from Hour Boutique for filming this video.

You can visit their shop at Peninsula Shopping Centre.

The Miyota caliber 8204 (8204A) is a 21 jewel automatic movement, first introduced in 1977 (other versions as early as 1974). This movement is from the Miyota 8200 family (aka 8 or 82 series) of movements. This 8204 has been discontinued by Miyota/Citizen and is no longer offered in their catalog of movements. It has evolved into the current Miyota caliber 8205.
