The Uni-Racer is a modern interpretation of the cult classic, with each detail painstakingly re-edited with a modern sensibility, down to the smallest detail.


Three years in the making, the Massena LAB Uni-Racer is a testament to the art of defying the rules and creating a timepiece informed by the past, but with a “Big Eye” on the present. The Uni-Racer is a 21st-century interpretation of a mid-century classic, with each detail of the watch painstakingly re-edited for the modern watch wearer. The Uni-Racer features a 39mm stainless steel case, finished horizontally for added visual interest. Massena LAB is proud to offer the Uni-Racer available in three new colorways, each evoking its own sense of adventure: Cruise, Safari, and Rally.

The tropical green dial of Safari features two silver and khaki subdials: a "Big Eye" 30 minutes counter and a small seconds counter. Taking a closer look, the wearer can appreciate the specific and shifting blue color of the subdial and chronograph hands, which was achieved through an arduous process of using traditional hand heating, oxidation, and other metal treatments. A keen eye will notice the engraved "M" logo in the acrylic crystal, reminiscent of the old days. As the company names implies, the Uni-Racer was created through a process, much like a laboratory experiment, but the final product is a timepiece that is meticulously crafted, rich in details and history, and intended to be a new cult classic beloved by connoisseurs and casual watch fans alike.
