The brand's name is "m/s Batory with 'Big Date' – Roman" (Roman numerals on the dial). Specs from its technical specification: 40mm (without crown) case, WR 100, screw-down crown, domed sapphire with inner AR, Seagull ST2525 class AAA "modified in Poland by G.Gerlach" with big date and central seconds (the base caliber also has day and month displays, which this dial doesn't show), crystal caseback as an option. 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.
