Islander Calabro GMT World Time Automatic Watch with Anthracite Dial #ISL-316

Islander Calabro GMT World Time Automatic Watch with Anthracite Dial #ISL-316 offers excellent value at $329 MSRP, featuring a handsome anthracite dial with applied indices, a sapphire crystal, and a quality 120-click unidirectional bezel.

Overall, owners rate the Islander Calabro GMT World Time Automatic Watch with Anthracite Dial #ISL-316 highly for its value and feature set at the price point.

Grand Seiko SLGW003

The Grand Seiko SLGW003 is praised for its comfortable, lightweight Brilliant Hard Titanium case, meticulous finishing, and a clean, modern dial. Reviewers highlight the new 9SA4 manual-wind movement, noting its attractive finishing, 80-hour power reserve, and accuracy of -3/+5 seconds per day. It is considered a versatile dress watch blending vintage and future Grand Seiko spirit. The €11,700 price is noted as expensive, with some questioning its value. Overall, reviewers rate the Grand Seiko SLGW003 highly for its elegant design and impressive manual-wind movement at its flagship price point.

From video reviewers

The slim profile of the Evolution 9 case is a key strength. Water resistance is a weakness, with figures of 50 meters and 30 meters cited. Reviewers disagree on whether the manual-wind Hi-Beat movement is a rarity or a notable addition.
