Founded by French artist and designer Romaric André, seconde/seconde/ is a design studio specializing in the customization of vintage and modern watches, specifically their hands. The watch hands designed by seconde/seconde/ are made in France by the only remaining workshop in the country that still manufactures watch hands.

In 2020, Massena LAB partnered with seconde/seconde/ to produce a special, friends and family exclusive edition of the Massena LAB Uni-Racer entitled "Hmm...Looks Familiar: a Massena LAB Uni-Racer Story".
