What people say

Owners + reviewers, side by side

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

Astor + Banks Fortitude Pro

Owners and reviewers widely praise the Astor + Banks Fortitude Pro for its scratch-resistant coating, thin and compact 38.5mm case, and versatile dial options. The layered finishing with polished chamfers and comfortable bracelet are frequently highlighted as strong points, contributing to its wearability. One owner notes good timekeeping, while a reviewer states the Miyota 9015 movement is adjusted to +/-10 seconds per day. A potential drawback mentioned is the date numeral appearing in half shadow due to anti-magnetic shielding, and one owner considers the bracelet clasp dated. Overall, owners and reviewers rate the Astor + Banks Fortitude Pro highly for its durable construction and thoughtful design at its price point.

Zelos Spearfish 3

The Zelos Spearfish 3 is widely praised for its exceptional finishing, with razor-sharp polish and flawless brushed transitions that owners feel exceed its price point. The 40mm case is noted for its wearability, and the La Joux-Perret G100 movement offers a 68-hour power reserve, with reported accuracy averaging +2.6 seconds per day. Reviewers highlight the exceptionally smooth bi-directional bezel and a tool-less micro-adjustment clasp described as best-in-class among microbrands. The sapphire sandwich construction and lumed bezel are also cited as desirable features.
