About this entry
47% of key specs known. Missing: lug-to-lug, thickness, lug width, weight, hardening, crown, lume, bracelet offered.
Specs from the brand's technical specification: brushed 316L 44mm case, WR 100, unidirectional bezel with ceramic insert, NH37 automatic (the photos show its small 24-hour subdial), double-domed sapphire with AR coating. Both listings were out of stock on 2026-10-31, so status is unknown. The brand's store is bilingual and lists the watch twice, as a Polish and an English product at the same price; both pages are listed as stores and prices cite the English one.
