H. Moser & Cie.’s retrograde-seconds trio uses the same visual rhythm across three collections: a hand travels through a 30-second arc, then returns to its starting point. The Pioneer Skeleton exposes its HMC 251 automatic movement in a 40 mm steel case and includes a steel bracelet and khaki rubber strap. The Streamliner pairs a Midnight Blue fumé dial with an integrated steel bracelet, while the Endeavour uses a Blackor fumé dial and leather strap. Both use the HMC 252 calibre. Moser specifies 72-hour reserves for all three, with water resistance of 12 ATM for Pioneer and Streamliner and 3 ATM for Endeavour. October 7 is the dated MOSSO release coverage; the linked manufacturer pages are undated.
