Every year Blancpain (as well as its sister company Breguet) debuts a limited edition for Valentine’s Day. The concept is a bit kitschy – the watch is usually decked out in diamonds and hearts – but this year’s edition is a notably interesting watch.

The Saint-Valentin 2020 is powered by a newly-developed form movement, the cal. 510, that is both rectangular and skeletonised. While traditionally Jaeger-LeCoultre has been the leader in form movements for ladies’ watches, most notably with the tiny cal. 101 and with other movements found in the Reverso as well as various Cartier Tanks, Blancpain has notched up a win in the segment with the cal. 510.
