Tissot RockwatchvsTissot PR 100

The Tissot Rockwatch is widely praised for its innovative use of solid Swiss granite for the case and dial, with each piece featuring a unique pattern derived from materials like the Jungfrau mountain. Reviewers highlight its quirky charm, tactile experience, and historical significance as a business success for Tissot during a difficult period. The 38mm case size and short lug-to-lug measurement contribute to its wearability. However, the included black leather strap is considered decent at best and could be improved. Overall, reviewers celebrate the Tissot Rockwatch for its unique material, historical importance, and distinctive aesthetic.

Owners widely praise the Tissot PR 100 for its exceptional value, with many noting its sapphire crystal, robust build, and attractive design. The Powermatic 80 variants are particularly lauded for their 80-hour power reserve and accuracy, with some reporting deviations as low as +/- 1-2 seconds per day. Owners appreciate the clean dials and practical clasps, finding the 39mm and 40mm sizes versatile. However, some owners report the crystal easily picks up fingerprints, and the stainless steel case and bracelet can show scratches or wear over time, with one instance of a bracelet falling apart after five years. Some also note that only the hands have lume, and the seconds hand may not perfectly align with markers on certain quartz models. Overall, owners rate the Tissot PR 100 highly for its impressive value and solid construction, making it a well-regarded entry-level Swiss timepiece.
