Tissot Seastar Sonorous Ref. 40500-3X circa 1970 | steel hand wound alarm wristwatch

This model incorporates the movement manufacturer A. Schild’s popular alarm calibre (cal. 1475). In addition to Tissot, the cal. 1475 was used by a variety of different manufacturers, including Tudor for their Advisor model and Movado for their Ermetophon purse watch. A manually wound movement, the alarm’s sound is created by a ‘hammer’ rapidly striking a pin welded to an inner movement cover, this is a similar system to that adopted by Jaeger-LeCoultre for their Memovox model. The watch is wound and the time set via the lower crown, the upper crown winds the alarm barrel; pulling this crown out allows the alarm to be set by moving the central red hand. When the alarm is set, the upper crown is left in the ‘pulled-out’ position until the alarm sounds upon which, if the crown is pressed back inwards, the alarm is silenced. View the video to see and hear the alarm in action.

In very good condition the dial has a great monochromatic look and a vertical satin finish which matches the grain of the upper case. The luminescent dots and panels to the hands glow well, indicating that they have been refreshed at some stage in the past. This watch is fitted with a herringbone patterned, Italian-made, steel bracelet which appears to be contemporary with the watch and compliments its styling. Fully adjustable via a sliding clasp, the bracelet can also be detached and replaced with a leather strap if preferred.
