Hand-wound, time-only 11½-ligne caliber of ETA's 2800 family: in effect the no-date, rotorless version of the 2824-2 (the 2804-2 is the same with a date). ETA product page: Ø25.60mm, 3.35mm high, hours, minutes and centre seconds, time setting with stop-second, manual winding, 28,800 vph (4 Hz), 17 jewels, Etachron regulator, "typical power reserve: 50 hours"; ETA files it under "Phased out". Caliber Corner gives 42h (the older figure), a 50° lift angle, Incabloc or Novodiac shock protection, and notes that stop-seconds and fine regulation were options on early examples; it was introduced around 1982. Its Sellita counterpart is the SW210-1 b (the no-date SW210-1; see sellita-sw210-1 for the date version).
