Bell-Matic 4006-6031 - Crown

Positioned at 3 o’clock, the original signed crown works in tandem with the pusher at 2 o’clock to control the alarm function. This dual-control system is an integral part of the Bell-Matic’s identity, allowing easy alarm setting without disturbing timekeeping.

Seiko Bell-Matic Leather Strap

This example is paired with a high-quality red perforated leather strap featuring white stitching. While not original, it complements the watch’s vintage aesthetic and offers a comfortable fit. Originally, the Bell-Matic was delivered with a stainless steel bracelet.

Heritage of the Seiko Bell-Matic in the 1970s
