Three-hand quartz without date from Ronda's 500-series (Powertech) line, the line that also includes the 505 (date). Ronda's own caliber page could not be read (it serves a bot check) and no Ronda spec sheet was found, so size, height and accuracy are left blank. Masters in Time's movement database lists it as a Swiss Ronda quartz with hours, minutes and seconds hands, hacking, a 371 / SR920SW cell and up to 45 months' battery life (recorded as 3.75 years). Cincinnati Watch Company, which uses it in the Ladies Guild, describes its "Ronda 503 Top Grade (Swiss Made)" as a repairable metal quartz movement with 1 jewel, stop seconds and "3-year battery life"; the jewel count is from that listing.
