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 Rotocall

Owners widely praise the Seiko Prospex Rotocall for its charismatic retro design and comfortable 37mm size, with many appreciating its space-faring heritage. However, multiple sources criticize its price point, suggesting it is too high for an all-digital quartz watch with features like a stamped clasp, mineral crystal, and standard quartz movement. Some owners also note drawbacks such as a flimsy battery mount and split pin bracelet construction. On balance, owners and reviewers find the Seiko Prospex Rotocall visually appealing and a faithful re-release, but its value proposition is frequently questioned due to its price.

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.
