Rotary Aquaplunge

Rotary Aquaplunge

A highly collectible quality Swiss 666ft diver with interesting features like the 13-24 hr markers. broad arrow hands (on first version) and rotating black bezel. First seen circa 1960 in non-date version and later with date.

Radium dials normally have large broad arrow hands and are non- date. The later versions can have red hands especially with the date version, which is a quickset movement. Later date models also have a large screw down bullet crown similar to Technos SkyDiver and Titus Calypsomatic.

This model was also sold, possibly under licence with brand names Iaxa. Baylor. Lator, Difor, LePhare and others.

Note that the change of dial and removal of Rotamatic text seems to coincide with the hands changing from broad arrow to a straight format (sometimes red). A very early radium non-date version has been seen with a red large arrow hour hand.
