Miyota 9015 Automatic - Manually Winding

[UltrasonicBokeh]

Hi,

I've recently acquired a Kent Wang Bauhaus V3 that's driven by a Miyota 9015 automatic movement. The crown in first position can be used to wind the mainspring. When I rotate the crown in a clockwise motion, however, it feels as if its ratcheting maybe 50 times per full turn. Is the watch properly winding or is it perhaps fully wound and this is the clutch I'm feeling? The watch was already ticking when I pulled it from its packaging!

As a note, this is my first automatic watch, though I've wound manually-wound movements (Seagull ST19) before. Power-reserve seems fine and it's keeping great time.

Thanks in advance for any experience someone here can share.

Today, DHL delivered my AP RO with the 9015 movement. It is doing the same thing as yours and I know exactly what you mean about it "ratcheting". I read another thread here and the OP reported the same thing too. I assume everything is normal, but would like to know (for sure) if this means the watch is fully wound. I suppose the watch could be allowed to wind down and you could start turning the crown to see at what point the same resistance is felt. Maybe someone else with knowledge about the 9015 movement could chime in and help us out...

Here's a link to some info on the Miyota Movements (just scroll down to find the 9015): http://www.citizen.co.jp/miyota_mvt/download/index.html

I've worn the watch for a little over a week now and haven't had any problems... The crown does seem easier to turn when winding after the watch sits for a prolonged period of time, so I don't think it's the clutch kicking in to protect the mainspring that we're feeling. A friend's Ball winds the same way, so I think it's safe to say we can enjoy wearing our Miyotas worry-free!
