These elegant cufflinks are made from Vintage Fontainemelon watch movements.
Their size fits perfectly on the sleeve of any shirt.  Just look at the dippled texture of the metal work.
Fontainemelon was founded in 1793 by Isaac & David Benguerel and Julien & Francois Humbert-Droz. 
They hand crafted watch movements and watch parts that were used by most of the Swiss watchmakers of the time.
We have made these cufflinks in our Wiltshire, UK, workshop.
These come to you in a gift box
Watch movement size 18 x 15 mm
