Quartz chronograph from Ronda's Startech line. Ronda's own caliber page and data sheet could not be read (the site serves a bot check), so the figures come from Caliber Corner, citing Ronda: 12½ lignes, 28.60mm overall (28mm casing diameter), 4.40mm high, 395 / SR927SW cell, 54 months' claimed battery life (recorded as 4.5 years), battery-saving stop when the stem is pulled, and a layout of central chronograph seconds, small seconds at 3, 12-hour counter at 6, 30-minute counter at 9 and date at 4. Made as a gold-plated Swiss Made version with 13 jewels and a nickel-plated Swiss Parts version with 6 jewels, so `jewels` is left blank. Masters in Time agrees on the cell, the 54-month battery life, hacking, the small seconds, the date and the 30-minute and 12-hour counters with 1/1-second centre chronograph hand. Accuracy is not stated by either source. Tier "mid" alongside the other Ronda 5xx quartz calibers and the Seiko VK6x chronographs.
