The UNIMATIC x Massena LAB U1-MLBN is a friends and family exclusive version of the U1-MLB, our third and final watch in a trilogy of three collaborations with UNIMATIC following the release of both ML6 and MLM in 2020. 

ML6, with its red triangle on the bezel and its tropical dial was born from a question: "what would a UNIMATIC watch from the 1950s look like today?” MLM, with its blue dial and bezel, was inspired by the dive watches issued to the French Navy in the 1960s.

MLB “Bund” represents a final evolution and is inspired by the dive watches of the 1970s, particularly the cult Blancpain “Bund”, which was issued to the West Germany’s Bundeswehr Kampfschwimmers, a group of elite special forces of the West German Navy.

MLB features an all black dial, with a black on black “ghost" signature to maximize the legibility of its ivory Super-LumiNova indices. Like the “Bund” of the 1970s, the dial of the MLB is characterized by a large, distinctly orange minute hand to differentiate it from the hour hand, both of which are luminous. 

The rotating bezel of the MLB features a single, large plot of Super-LumiNova at 12 o’clock, which is referred to as a “sterile bezel”.

MLBN, available only to our family and friends, is an all-black take on the MLB and features a matte black DLC-plated stainless steel case, an all-black DLC-plated bezel, and a matching black TPU strap.

On its case back, MLBN is engraved with a submarine sonar motif, along with its limited-edition number.  MLBN is delivered with two straps: one in black and another in burnt orange, both made in Italy from TPU and signed UNIMATIC.

MLBN is a limited-edition of 80 pieces exclusive only to our family and friends.

Limit of one watch per household.
