One of my students has a device on her Astra IIIB that I have never seen elsewhere. It is an electronic stopwatch/lap timer specifically adapted for use as a sextant timer. The mount is an L-shaped metal bracket on the sextant's handle. The bracket is held to the sextant's handle with the
handle's own upper illumination battery compartment screw. One of the normal stopwatch buttons has been removed and replaced with an external pushbutton which mounts on the front of the handle so that the index finger can reach it
easily. It looks like it will mount nicely to any sextant with that handle arrangement, but it could be an Astra IIIB exclusive. (The sextant was purchase second hand with the timer, so the original source of either is unknown. Ken Gebhart - I checked Celestaire catalogs back to 1991 and could not find it, but I could have missed it.) It is a SighTime Model 911-B. You zero and start it at a known accurate time with a recessed button on the device, and each time the external button is pressed the elapsed time since synchronization appears on the display and remains until the button is pressed again, when the new value is shown.
A Google search turns up nothing. Is anyone else familiar with it?

The Casio W96H digital watch meets quite a few requirements for a dedicated sextant watch.
