Christie's June 11 auction, A. Lange & Söhne, Audemars Piguet, Vacheron Constantin, Omega and pocket watches
These are my picks for the upcoming auction on June 11 at Christie's. I choose some A. Lange & Söhne, Audemars Piguet vintage Chrono, Vacheron Constantin vintage Chrono and a beautiful Omega made in 1936 (37.5mm).
I start with the A. Lange & Söhne Datograph flyback chrono made in 2005 and cased in platinum. Lot N°166. Estimated 30 000$ - 50 000$.
The A. Lange & Söhne 1815 Chronograph is for my personally one of the most beautiful watches made by Lange. This one comes in white gold and was made in 2000. Lot N°164. Estimated 15 000$ - 20 000$.
A. Lange & Söhne Grand Lange 1 with black dial and luminous indexes made in 2010. Lot N°165. Estimated 18 000$ - 22 000$.
Audemars Piquet Chronograph made in 1946 with the highly sought-after mouvement 13VZAH. In 1946 Audemars Piguet produced only 853 watches overall and there were only 18 with the 13VZAH movement made. Lot N°234. Estimated 30 000$ - 50 000$.
Vacheron Constantin reference 6087 made in 1955. There were only 36 examples made of the reference 6087, 26 in yellow gold, 8 in pink gold and 2 in platinum. So this one is a quite rare watch beautifully designed with its unusual lugs. Lot N°233. Estimated 20 000$ - 30 000$.
And an other wristwatch made by Vacheron Constantin, reference 4072, made in 1940. Lot N°232. Estimated 12 000$ - 18 000$.
Beautiful Omega steel wristwatch made in 1936 and for that time with oversized case of 37.5mm in diameter. It does have a beautiful sector dial. Movement 26.5 SOB T2. Lot N°190. Estimated 5 000$ - 8 000$.
And then we come to the pocket watches. I start with a beautiful minute repeater made by Charles Frodsham in 1885. Lot N°128. Estimated 6 000$ - 8 000$.
A very beautiful Patek Philippe minute repeater with perpetual calendar and moon phases made in 1890. Lot N°141. Estimated 40 000$ - 60 000$.
An extremely rare and very impressive Tiffany & Co. minute repeater with split seconds cronograph. The more this really beautiful pocket watch is set with diamonds, ruby and sapphire. Lot N°142. Estimated 100 000$ - 150 000$.

Marc Jenni, the way of his new in-house movement. Pt5, Pt6 & Pt7
Marc Jenni: Notes like these help me programming the CNC machine- each circle, arch, bow or hole needs to get referenced with its own position and depth.
Marc Jenni: When finally the CNC program is written, the fun may begin. You can spot the cut-out circles for the wheel train. View on my vintage Olivetti computer from 1995 with a CAM program running on Windows 3.1.
Marc Jenni: And back to the brass plate where the 0-position for the Z axis needs to be determined. (Check out the two little circles on the upper level of the plate). This process happens every time a milling cutter or a drill needs to be changed.
Kind regards.
