Reference sources reviewed 7 November 2026. Published specifications, not independent measurements. Versions and complete-watch specifications can differ; fields without a verified figure are omitted or identified.
What distinguishes it
Look beyond the reference.
It runs at 3 Hz and is 5.67 mm high. Miyota’s current listing includes stop seconds, which allows the seconds hand to pause during time setting.
For the enthusiast
The maker offers calendar variations, so the numeral orientation, window position and language deserve attention when identifying an example. Current specifications should not automatically be applied to every older watch carrying the same base reference.
