What people say

Owners + reviewers, side by side

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

Sartory Billard SB10

The Sartory Billard SB10 features a unique jumping hour and perimeter hour ring design, with functional grater plates that are not practical for actual grating due to a blocked-off side. Owners note the absence of a seconds hand, minute tick marks, and a conventional crystal. On balance, owners appreciate the unique design elements of the Sartory Billard SB10, despite its impractical features.

Spinnaker Croft 39 GMT

Owners praise the Spinnaker Croft 39 GMT for its colorful design, NH34 GMT movement, and reasonable price, noting high-standard manufacturing on the case, bezel, and bracelet. One owner finds the 43mm case and 51mm lug-to-lug dimensions too large for the design, preferring a 39-40mm case size. A potential issue with the lume was noted by one user. On balance, owners value the Spinnaker Croft 39 GMT for its attractive design and build quality at its price point, though sizing is a point of contention for some.
