Cal. 43.15 S “Grade Very Best”

The “Grade Very Best” replaced the “DDR” as Omega’s highest quality chronometer movement in July 1922. This calibre was made in 600 examples: 300 “Lépine” movements (for open-face watch) and 300 “savonnette” movements (for hunting-case watch).

The term “Very Best” was trademarked by Omega for dials, cases and movements in 1904.

The present watch cost 1 085 Swiss francs in 1929.By way of comparison, that same year Tiffany & Co. sold a Patek Philippe minute-repeating perpetual calendar pocket watch with moon phases, split-seconds chronograph and 30-minute counter for 2 835 Swiss francs, and a standard 18K gold hunting-case pocket watch with 20’’’ movements could be bought for 385 Swiss francs.

The fact that this watch cost nearly 40 % as much as a highly complicated Patek Philippe and over four times as much as that company’s standard production is due to the cost of manufacturing such a high-precision movement.

Precision movements are made to much smaller mechanical tolerances than standard watch movements and often take as long to manufacture and regulate as complicated movements. Precision watches were also prized possessions and were often reserved for the manufacturer’s best clients.
