An interesting time in the workshop
today, as I started working on my first Stop Watch. This one is a Swiss Made
TIM LEVER 7 Jewels Shock Protected, and the movement is a (BFG) BAUMGARTNER
FRERES S. A. GRENCHEN (Suisse), Calibre 410. This calibre is used by Breitling on
some of their stopwatches, so movement is of good quality. Rear case markings
are Antimagnetic – Self Compensating - Shock Protected.

Next, I removed the fly-back
lever, so I could remove the broken fly-back pusher. Don’t think I’ll get a
replacement for this, so will have to make one on Boley 6.5mm Watchmakers lathe
later.

First I had to remove the front
bezel to get to the movement as the back of the case is made part of the case.
(Crystal needs refitting into Bezel).
Next, remove hands, small minute
hand removed normally, but the second would not budge, so removed the dial (2
Screws). The dial easily came away, and looking under the dial the Second hand
is fitted to a heart-shaped cam, so left that alone for the time being. Will
leave the cam in cleaning jar, while the dial not touching the fluid.
The movement came free from the
case with just a plastic stem bridge part holding the movement in.
So taking photographs I go, I completely
deconstruct the rest of the movement.
Found the parts sheet online for
the movement, so put part numbers in the picture info section.
So just need to release the
Second hand from the dial, and strip down the barrel before cleaning the parts.
