The Vulcain 402 watch movement features a pin-lever escapement and an indirectly driven minute hand, allowing for a large balance and low profile. It has the option for shock protection through elastical spiral balance spokes and is often or always identified by its 8810 signature. The movement offers various functions, including a manual wind stop minute, a continuously running center minute that can be reset with a pusher at 2 o'clock, a sub-second display, and a date function that can be set within a +/-24-hour range. The Vulcain 402 movement was predominantly used during the period around 1975.
