What people say

Owners + reviewers, side by side

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

Oak & Oscar The Humboldt GMT SAR Edition

Oak & Oscar The Humboldt GMT SAR Edition is praised for its anti-magnetic properties, sandwich lume dial, and overall construction quality for its price point. It features a brushed Grade 5 titanium case, a navy blue sandwich dial with an orange minute track and seconds hand, and a Sellita SW330 movement with a 56-hour power reserve. Minor drawbacks noted include bracelet sizing adjustment and lume brightness. On balance, owners and reviewers rate Oak & Oscar The Humboldt GMT SAR Edition highly for its robust construction and unique dial design 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.
