We love the fabulous Rotary logo's on the wheels of these mechanisms.
These wonderful pieces of craftmanship date from between the 1930's to 1950's.  
Rotary was established in 1895 by Moise Dreyfuss in the town of La Chaux De Fonds, Switzerland.
In 1940 Rotary was appointed official watch supplier to the British Army in World War 2.
The cufflinks have been handmade in our Wiltshire workshop. 
These come to you in a high quality gift box
