A Unique Thai Twist on the Classic California Dial: Unveiling the Serica Ref. 6190 TDM

Published: 04 Mar 2026
Introducing the Serica Ref. 6190 TDM, an incredible timepiece inspired by Thailand and a new take on the famed California dial.

In the horological world, the dial of a watch is often its defining feature. Among these, the so-called California dial, a creation from the 1930s, holds a special place. Its unique design merges Roman numerals on the top half and Arabic numerals on the bottom half, a deliberate choice aimed at enhancing legibility. It’s eminently cool and classic, but for Serica, it also represents an opportunity - a chance to innovate.

That’s just what they’ve done with the Ref. 6190 TDM (Thing Death Match). This extraordinary timepiece is all about Thailand. Conceived exclusively for the Thai Domestic Market, Serica uses the traditional California dial as a starting point, and then boldly transforms it into something incredibly unique. The standard concept has been revolutionised with the utilization of Thai numerals, creating an intriguing and original variant unlike any seen before.

Yet, it’s the dial of the Ref. 6190 TDM that truly sets this watch apart. The dial retains most of the classic layout of the California dial, with a clear railroad minute track, a mighty triangle at 12 o’clock, baton markers at 3, 6 and 9 o’clock and Roman numerals on the top half. The dial, possessing a polished black enamel-like surface, imbues the watch with an individuality that perfectly compliments its creative approach to the admired California dial design and the numerals inspired by Thailand.

In summary, the innovative Serica Ref. 6190 TDM stakes its claim as a fascinating addition to the world of horology, innovatively blending elements of Thai culture with classic watch design. This unique timepiece is an exciting step forward, daring to reimagine the traditional California dial through a Thai lens.
