P1160277A customer has sent in his Patek Philippe calibre 30-300 PM for a service.

P1160234

Movement does not look especially dirty, but there are some fibres here and there.

P1160273

Dial and hands before I remove them.

P1160238

I notice there is a little more dirt on the dial side.

P1160242

I now start taking apart the gear train. 

P1160244

Here you can see some of the gear train exposed.

P1160246

I will take out the mainspring and clean it.

P1160263

Movement cleaned and ready to be put back together.

P1160264

Mainspring is oiled and put back into the barrel.

P1160265

I see that the balance moves freely after fitting the shock jewels.

P1160266

The ratchet wheel is placed on the underside of the barrel bridge.

P1160267

I fit the barrel and barrel bridge.

P1160268

I now fit the setting/winding mechanism.

P1160269

The gear train goes back into the movement.

P1160270

I’m happy to have a ticking movement again! I must say it does look very nice.

P1160280

That’s good enough for an old Patek;)

Ready for dial and hands.

Dial and hands back in place
