New Men’s Style OBGYN Gestational Calendar Watch

New and unused albeit quite niche watch for an OBGYN, but hey… that’s what the internet is for, right? Needs new battery. External dial has weeks of the year and internal dial has gestational weeks from last missed period. Quartz circuitry, silver and gold band to 8.25” with 1” of additional extension links included. Comes with the enclosed wooden box.
