Tissot PRC 100 watches

The Tissot PRC 100 is a sports watch line from Tissot, the Swatch Group brand based in Le Locle, first introduced in the mid-2000s. The original watches come in steel or titanium cases with sapphire crystals, as plain three-hand models and as chronographs, from a compact 29.7 mm up to 42 mm.

The PRC 100 Quartz is the small three-hand watch, 29.7 mm across and 8.5 mm thick. The T008.010 references cover silver, black and mother-of-pearl dials, with a titanium version (T008.010.44.061.00) and a Two Tone with mother of pearl (T008.010.22.111.00). The PRC 100 Quartz Chronograph is the step up at 34.8 mm, in the T008.217 references with silver, brown or mother-of-pearl dials. The T22.1 references take the same two sizes and add a gem-set bezel: the three-hand T22.1.181.21 pairs it with mother of pearl on a bracelet and T22.1.161.81 with a red dial on a strap, and the chronographs T22.1.456.21 and T22.1.466.81 follow the same pattern.

The larger watches are a different shape of PRC 100. The 41.3 mm PRC 100 Quartz in the T22.1.581 references is a 10.3 mm steel three-hand on a bracelet, with black, blue or silver dials. T008.417.44.061.00 is a 41.3 mm titanium chronograph with a black dial, and T008.414.11.201.00 a 42 mm steel watch with a black carbon dial in a 14.2 mm case.

The current PRC 100 Solar reinvents the 2000s original. It is a 39 mm, 9.22 mm steel watch with a twelve-sided bezel and a Lightmaster Solar quartz movement that, fully charged, keeps running for up to 14 months in complete darkness. It is water resistant to 100 m and takes a 20 mm strap.
