What people say

Owners + reviewers, side by side

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

Seiko Prospex SPEEDTIMER

Owners widely praise the Seiko Prospex SPEEDTIMER for its unique dial colors and vintage-inspired design, with many appreciating its compact 39mm case size and 100m or 200m water resistance. Reviewers and owners note the V192 solar movement’s power reserve indicator and its reliability, though some owners express a preference for automatic movements. One owner finds the $700 price for a solar quartz model expensive, while another criticizes the €860 price point and desires a thinner case and a bracelet with quick-release or micro-adjustment. On balance, owners and reviewers appreciate the Seiko Prospex SPEEDTIMER for its distinctive aesthetic and versatile wearability, despite some reservations about its price and case thickness.

Tissot PRC 100 Solar

Owners and reviewers highlight the Tissot PRC 100 Solar's value and modern, urban aesthetic, with its slim 9.2mm case and good finishing for the price. The solar movement is a key feature, offering a 14-month power reserve and rapid charging capabilities. Some owners find the dial colors a bit uninspired, and the date window placement is disliked, while the second hand's ticking is noted as a drawback compared to automatic movements. The watch's 39mm case is considered versatile, though some prefer a smaller 35-37mm size. Overall, owners and reviewers consider the Tissot PRC 100 Solar a versatile daily wear, particularly for its solar technology and Swiss-made appeal at its price point.
