Ernest Borel Valjoux 23 Movement

Resurrection of a dead chronograph movement

This post pertains to a Valjoux 23 chronograph movement which was received in the same freezer bag from China as the Universal Genève Uni-Compax I recently serviced. The bag contained multiple chronograph movements which were all in bad shape. I actually received two Valjoux 23 movements, but this one had a working balance and Incabloc shock protection thus making it the better candidate for restoration.

Universal Genève Uni-Compax

Service of a Martel chronograph movement

Here is what I consider to be a very special piece even though it’s missing some of its most important bits. This is a Universal Genève Uni-Compax chronograph from around 1942. The movement was most probably fitted in a solid gold case which at some point went to the smelter and may not be replaceable. Regardless, I was excited to get my hands on the piece because it’s a chronograph movement I’ve not worked on before. Continue reading “Universal Genève Uni-Compax”

Favre Leuba Chronograph

Service of a Valjoux 71 Chronograph

As I was flipping through a price guide published for watch collectors I halted on a picture of a timepiece with a very interesting complication. The watch in question was produced by Favre Leuba in the early 1960’s and in addition to the standard mechanical movement it also housed an aneroid barometer for the purpose of determining altitude. The watch is known as the Bivouac and is quite rare and prized by collectors. Continue reading “Favre Leuba Chronograph”

NASA Moonwatch Strap

Final outfitting for my Speedmaster project

If you scroll way down to the bottom of my blog you’ll find a link to the Speedmaster project that I completed many months ago. At the time I considered the job “done” even though there was a very important piece missing to the watch- the steel bracelet. Continue reading “NASA Moonwatch Strap”

Bradley Mickey Mouse Watch

Back in the day even children’s watches were mechanical

This is a Mickey Mouse watch made by Bradley from the 1970’s. Like most of the watches I’ve worked on it is a manual wind movement (quartz movements still being a bit pricey at the time of manufacture). The movement is a Baumgartner 134 which is Swiss made, but instead of using a Swiss Lever escapement, this movement utilizes the cheaper Pin-pallet escapement. Continue reading “Bradley Mickey Mouse Watch”

Black Dial Pierce Navigator

Restoration of another Pierce Navigator

As anyone who has invested a little time perusing this blog will know, I have a hard time passing up an affordable chronograph that is in need of some TLC and so it is that I found myself with another Pierce Navigator in less than pristine condition. Continue reading “Black Dial Pierce Navigator”
