What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Tissot Le Locle Open Heart

Owners widely praise the Tissot Le Locle Open Heart for its elegant aesthetic, featuring a guilloché dial and Roman numerals, and appreciate its practical 80-hour power reserve and Nivachron hairspring. The watch is also noted for offering dual bracelet and strap options, along with a see-through case back. However, one owner flags negative community feedback regarding the comfort of the synthetic leather strap. Overall, owners rate the Tissot Le Locle Open Heart highly for its attractive design and impressive technical specifications at its price point.

Tissot PR 100

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.
