What people say

Owners + reviewers, side by side

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

Marnaut Safe Harbour 100C

The Marnaut Safe Harbour is widely praised for its compact 39mm tonneau case and its unique sea urchin-inspired dial. Reviewers note the case wears well despite its 13.2mm thickness. One owner flagged a potential lume inconsistency, which was attributed to UV lighting effects. The slender handset can be difficult to read against the busy dial, and the faux-crocodile strap is stiff initially. Overall, owners and reviewers appreciate the Marnaut Safe Harbour for its distinctive dial and comfortable wearability.

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.
