Speedmaster 145.022-69 Power reserve

SPEEDYMARTIN · Aug 10, 2024

Hello Speedmaster experts

I believe the new 3861 Power reserve is around 50hrs and the 1861 about 48hrs. But what about the earlier 861 movement?

what should be expected if full serviced and new mainspring?

Thanks for your help!

UPDATE

Hello

I just performed a power reserve test on my vintage Speedy and surprisingly achieved 52.5 hrs from a full wind. ☺️

I was wearing it normally during the test.
