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.

Seiko Prospex SPEEDTIMER Mechanical Chronograph

The Seiko Prospex SPEEDTIMER Mechanical Chronograph is praised for its handsome, heritage-inspired design with a clean, balanced dial and an external tachymeter bezel. Reviewers highlight the upgraded case and bracelet, noting improved comfort and good value for a well-designed chronograph with an in-house movement. The caliber 8R48 movement features a vertical clutch and column wheel with MEMS technology for durability and precision. Points to consider include the 4:30 date window and a 14.6mm thickness, while the 45-hour power reserve is noted as an area for potential improvement. On balance, reviewers find the Seiko Prospex SPEEDTIMER Mechanical Chronograph to be a solid offering with good value, particularly for its design and in-house movement.
