Ronda 500-series 11½ ligne quartz with date and a 24-hour disc read through a dial window (the 515.24H shows the same 24-hour indication with a central hand). Ronda technical instructions No. 314.3: Ø26.20mm overall, Ø25.60mm casing, 3.00mm high, No. 371 / SR920SW cell, -10/+20 s/month instantaneous rate at 23°C, 45 months' autonomy (recorded as 3.75 years), resistant to 1,500 A/m. Crown position 2 corrects the date and the 24-hour indication (so it can show a second time zone, set in steps); position 3 sets the hands with stop-seconds. Ronda's standard dial drawing shows the 24-hour disc in an arc-shaped window above 6 and the date at 3; watch brands place the windows to suit their dials. The jewel count (1) is from Unimatic's UT1-GMT spec sheet, matching Ronda's other 515 calibers. Tier "mid" per the guide's Ronda 5xx row.
