How to open this main spring barrel

[Edifred]

Hi all

I have a wrist watch that I think has either a broken main spreing or is gummed up, However I gave not come across a barrel such as the one pictured and cannot work out how to open it.

Help appreciated!

Put the barrel with the silver side and gears side up, push it down around the edge on something hard, the silver part with the gears attached will pop off. I use a watchmaker anvil.

The lid will pop off in the same as most other barrels,   Can you post a picture of the watch as well, this always helps as other may have worked on the same one.

Excellent. Thanks both. Picture of the parts attached for others as suggested.

Hi it’s a roskopf type barrel with min wheel attached, the method I use is on the square end up wards tap the arbour top with a watch brush back and it pop off. Mark the position of the slot in the cover so as to refit in the same place, not necessary really but just tidy.

Thanks for this. I have it open now but without think the spring and arbour would go into orbit. I was in idiot mode. Anyway parts found! Got lucky
