Another day and another unusual Seiko. This Champion is not running and not exactly living up to it’s name;) Let’s see if we can change that! Calibre 54-20-1
I really like these early 60’s Seiko manual winds, the movements are funky, reliable and have a great design.

Hello Mitka,
Lovely work as always. If the wacth still works and can be set wihen the setting lever spring is broken, what function dd it serve?
Best wishes

Sorry for the typos – watch, when and did – I hit return accidentally.
The setting lever spring helps hold the setting lever in position when setting the time. In this instance you can still pull the stem out to setting position and it will stay in position okay when setting the time. On some watches you would have to hold the crown in setting position when changing the time or it would move right back to winding position.
Hello Mitka,
Thanks for sharing thsi.
I’m working on a Cronos and have exact the same problems; setting lever spring unable to find it (or even cal 54 parts list) and also broken casing screws. It would be helpful to know how you did remove them and found the right new ones.
Hi Sven,
I managed to wiggle the screws out using a broken off screw extractor. But if thats not possible you can dissolve the broken off screw in a solution of Alum. 1. you boil water 2. Putt he water in a glass container. 3. Add a good amount of Alum. 4 Stir until the Alum dissolves in the water. 5 Put the bridge/plate in the water and wait for the screw to dissolve over night or as long as it takes.
Warning:
Can discolour some plates if left to long.
Remember to remove all other iron based materials from plate…X)
I think your might be an other version of the same cal 54
