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”

Breitling Navitimer 806

Servicing an iconic pilot’s watch

Before joining the echelon of luxury Swiss watchmakers, Breitling was one of the earliest purveyors of chronographs for the common man.  In the late 1920’s they sold their patent portfolio to Hann-Landeron and began using movements almost exclusively from the Venus company. Chronographs from Breitling were very much in demand during the 1940’s, 50’s and 60’s. Their most popular models were the Navitimer, Top Time, and Chronomat.

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”

Pierce Navigator Restoration

Restoration of a vintage single button chronograph

In sticking with the theme of repairing old chronographs, I picked up another Pierce Navigator a few months back from eBay in non-working order. This chronograph is a little bit different from the others that I have repaired in that it’s a single button chronograph. A single button chronograph is a closer relative to the stop watch since only one button is utilized for the start, stop, and resetting action. Continue reading “Pierce Navigator Restoration”

Gold Plated Pierce Navigator

Service and repair of a gold plated Pierce Navigator

Today I wrapped up service of the second Pierce Navigator chronograph that I purchased back in February of this year. This watch was purchased at the same time as the nickel plated Pierce that I serviced earlier but it took much longer to complete as there were numerous issues on the inside and it needed a bit more restoration work on the outside. Continue reading “Gold Plated Pierce Navigator”

Omega Speedmaster Professional

Restoring the original NASA Moonwatch

Four months back, convinced that I could repair a broken Omega Speedmaster for less than the cost of a new one, I took a flyer on a collection of parts that were being offered on eBay. The pieces, when assembled, would compile about ninety percent of the watch in question- a 1967 Omega Speedmaster Professional (model no. 145.012-67). Still to be acquired would be the dial, bezel, caseback, crown, pushers, and three missing hands. Continue reading “Omega Speedmaster Professional”

Thoresen Recipro-Register

A proper Landeron chronograph

Having repaired one of the oddball chronographs of the 1950’s, I now set my eye on a more conventional chronograph movement. My options, limited by my wallet, were confined to either a Venus, Valjoux, or Landeron calibre which were the most common of the period. There were others to be sure but the majority fell under these three Swiss manufacturers. Continue reading “Thoresen Recipro-Register”
