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.

Grand Seiko SLGB006

The Grand Seiko SLGB006 is praised for its stunning "Ice Forest at Dawn" textured dial and 37mm 18k yellow gold case, with some finding it gorgeous enough to wear even if they don't typically prefer gold watches. It houses the Spring Drive Calibre 9RB2 movement, noted for its "Ultra Fine Accuracy" of ±20 seconds per year and a 72-hour power reserve. However, the Grand Seiko SLGB006 is considered expensive by some, with a price of $43,600 or €44,700 for its limited production of 80 pieces, and one owner suggests alternatives offer a more refined feel. The watch lacks the Evolution 9 micro-adjustment system. Overall, owners and reviewers highlight the Grand Seiko SLGB006's striking dial and movement accuracy as its primary strengths, despite its high price point and limited availability.
