What's for sale?

This is the Swatch "Egeria" watch first introduced in their 2000 Spring and Summer collection. The model number is YMS100G.

It has a beautiful dial in royal blue and a highly polished stainless steel case and bracelet. The hour markers are luminous dots, as are the tips of the hour and minute hands, which have cut-out centres. It has a reliable ETA quartz movement powered by a 394 battery.

It's in their Irony Chrono Medium category, smaller than the standard chronographs and a suitable size for women too. The case is 35mm wide and 12mmm thick.  Personally, we prefer the size of the medium chronographs.

Chronograph refers to the stopwatch functions, which also lets you add times and do split timing.

How does a Swatch chronograph work?

The small dial at 6 o'clock is the normal, continuous second hand. The stopwatch uses the large second hand and the two small dials at top left and top right. Top left records minutes, top right records tenths of a second.

The button at 2 o'clock is used to start and stop the timer. Use the button at 4 o'clock to reset the timer to zero. However, if you restart the timer without resetting it, it will restart from where it stopped and add the times together.

The button at 4 o'clock resets the timer to zero when timing has been stopped by the upper button. But it will also give you a split time if you use this button to stop the timer instead.  Split timing freezes the stopwatch so you can read the time but carries on timing internally, the hands will catch up when you restart with this button. Clever stuff.

The main crown at 3 o'clock is used to set the time and recalibrate the chronograph dials.

The original manual is included.  Using the stopwatch functions are straightforward, but if you need to recalibrate the dials (e.g. if they weren't at zero when changing the battery), then this is also covered. A pdf version of their chronograph instructions is available from Swatch.
