A Chess Master and Clockmaker
Carlos Sobrino was a Mexican chess master as well as a chess-clock maker. He finished runner-up in the 1967 Mexican National Closed Championship in Saltillo, and later testimony remembers “Maestro Carlos Sobrino” giving simultaneous exhibitions in Mexico City. That competitive background is important to the clocks: Sobrino was not an outside instrument maker designing for a game he barely knew, but an accomplished player working from direct experience of tournament chess.
Carlos Sobrino - Mexican Chess Master and Clockmaker
Documented Mexican Manufacture
An instructional chess source identifies one surviving clock as “Reloj de fabricación mexicana, Carlos Sobrino” and associates Sobrino-made clocks with use during the 1970s, 1980s, and early 1990s. Collector confirmation supports the player-maker identification. Surviving examples include personalized clocks made for friends as well as reports of simpler clocks produced for ordinary sale, although no complete catalog or model list has yet been located.
Bespoke Production
Sobrino made personalized clocks for friends rather than limiting himself to one standard model. A surviving dark-dial clock uses a wooden case, red flags, and top buttons.

The 'El Ministro' Clock
Another surviving example has two chess dials plus a third central dial showing ordinary time of day. Labels such as 'El Ministro' and 'Gilberto' indicate personalization rather than a formal model name.

Ordinary Sale
Sobrino also produced simpler clocks for sale, although no complete catalog or model list has yet been found.
Historical Significance
Sobrino's clocks unite player culture and object manufacture unusually directly. They are not anonymous industrial products: the maker understood tournament chess from the inside and sometimes tailored the object to a particular recipient.
