Authentication
The Solo-37 is the 37mm case variant; verify case diameter before purchase to distinguish from the 43mm Solo.
Known issues in the market
- Case diameter is the primary Solo variant differentiator; lug proportions differ between 37mm and 43mm.
- The trip-tick barrel alignment check from the S301 applies to all Bremont trip-tick references.

Authentication guide
Last reviewed June 2026
The Solo 37 is Bremont's entry-level piece and the most accessible expression of the TRIP-TICK case. At 37mm it reads as a contemporary everyday watch rather than a sport tool. The TRIP-TICK case authentication is identical to all other Bremont models.
