Sartory Billard SB10vsZelos Comet 39

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.

Owners widely praise the Zelos Comet 39 for its wearable 39mm size, thin profile under 10mm thanks to its manual-wind Sellita SW215 movement, and its captivating dial with a deep starburst effect. The winding action is described as a joy, and the watch is considered a stunner for its price, blending modern and vintage aesthetics. Some owners note frustration with Zelos's limited production runs leading to quick sell-outs. One owner found the logo childlike, while another experienced strap-rubbing issues with the short lugs, which were resolved with a Milanese bracelet. Overall, owners and reviewers rate the Zelos Comet 39 highly for its excellent value and striking dial design.
