I am trying to use a theodolite with which I am trying to take precision sightings on stars, but a limiting factor is that virtually all quartz clocks/watches only tick off the whole seconds, which immediately limits me to 0.25 minutes of longitude. Is there a stopwatch out there that can be set to GMT so will act as a chronometer over a period of weeks or months, but has a feature where a button can be pressed and the display will show the time at which the button was pressed to a tenth of a second or better? Then, at another press of a button, current time is displayed once again in the normal way. Thanks.
