TIM LEVER 7 Jewels Shock Protected Stopwatch

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.

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.

 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.

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.
