Ultra-thin 10.5-ligne hand-wound caliber introduced by Peseux in the early 1970s; identical to the later ETA 7001 after Peseux was absorbed into ETA. Small seconds at 6, Incabloc shock protection, no stop-seconds. Ranfft gives a 23.7mm overall / 23.3mm casing diameter. Power reserve figures vary by source (42h on Ranfft, Monochrome and Worn & Wound; 44-46h on some databases); 42h recorded. No factory accuracy range found (Monochrome quotes a +/-7 s/day "middle rate"). Monochrome reports production paused in 2004, resumed as ETA 7001 in 2011, and that it is no longer obtainable from ETA for new customers, with the La Joux-Perret D100 as a successor.
