Nivada Grenchen DepthmastervsZelos Comet 39

Owners widely report terrific build quality and a feel similar to the 1960s original, with some appreciating its reasonable lug-to-lug and better-than-expected appearance in person. The compact 39mm case is praised for its wearability, especially on smaller wrists, and offers impressive 1,000m water resistance. However, the Soprod P024 movement's 38-hour power reserve is a point of criticism, as is a bezel that can be difficult to grip and weak lume. Some owners find the watch wears on the smaller side, and the date complication is seen by one owner as detracting from the design. The "Pacman" variant is noted as polarizing, with one owner questioning their purchase, while the "Ghost Purple" variant's 30 and 45 numerals are described as having a rushed aesthetic. Overall, owners and reviewers rate the Nivada Grenchen Depthmaster highly for its faithful reissue, impressive water resistance, and comfortable wearability at a competitive price.

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.
