Why Collectors Love This
The H. Moser and Cie. Pioneer Perpetual Calendar reference 3800-1200 combines the brand's sporty Pioneer case with a Midnight Blue fume dial in stainless steel. The 42.8 mm case gives it real wrist presence, but the overall design stays clean and restrained. On the dial, the perpetual calendar is laid out with unusual clarity, with the month shown through the hour markers and a central hand. A large date display keeps the watch easy to read at a glance. Inside is the manual-wind HMC 800 calibre, built as an integrated perpetual calendar movement. The calendar can be adjusted forward or backward at any time, a genuinely useful feature in regular wear. Water resistance is rated to 12 ATM, which suits the more versatile character of the Pioneer line. This example has a Midnight Blue fume dial and stainless steel case, a combination that gives the complication a more modern feel. Like New with H. Moser and Cie. box and papers dated 2020.
