 TMC was by far the most prolific chronometer maker ever; although it was first in terms of quantity, the firm stood also for quality and exclusivity - particularly during the years after World War II when limited series and unique pieces were introduced into its range of products.After a period without production, TMC was revived in 2012, and it now makes high-end chronometers for the luxury market with precious materials, with an emphasis on yachting.Although the UK no longer has a chronometer certification/testing system as the Greenwich Trials were suspended at the start of World War I and never reinstated, pinpoint accuracy is still a crucial feature of the 21st century chronometer.
