Miyota 6S20

Citizen (Miyota) · Quartz · Mid tier · Family: Miyota 6Sxx chronograph

Three-register quartz chronograph from Miyota's 6S family (6S10, 6S11, 6S20, 6S21, 6S30). Miyota's product page: 15 lignes, 4.90mm high, accuracy ±20 s/month, battery life 4 years, chronograph minutes/seconds and 1/20 second, date, shock detection; calendar variations with the date window at 4:30 (6S20-00A) or 6 (6S20-00Z). Miyota's 6S10/6S20/6S30 manual: central hours, minutes and chronograph seconds hand (1/4-second steps), chronograph timing to 59 min 59 s, a 1/20-second hand that runs for the first 30 seconds of a timing and then parks at zero. Caliber Corner gives the layout as small seconds at 6, 1/20 second at 3 and 60-minute counter at 9, with 0 jewels, SR927W battery, Japanese manufacture and hacking seconds; its 34.6mm diameter doesn't match 15 lignes (33.8mm), so no diameter is recorded until Miyota's drawing can be read. Tier "mid" alongside the other quartz chronographs in the database (Miyota 0S2x and 6S21, Seiko VK6x).
