Victorinox Infantry Vintage Jubilee Edition watch

This year, Victorinox celebrates its 125 years since it was founded and also its 20th Anniversary since its first watch was introduced. In line with this celebration, Victorinox has released two watches, both from the Infantry Vintage collection. The first is a red dial watch, Infantry Vintage Limited Edition which will be a limited edition run of 125 pieces. The other is a green dial watch, Infantry Vintage Jubilee Edition which will be a normal series watch.

The case back of both watches are very beautiful. The case back is engraved with Victorinox's anniversary seal, '125 years, your companion for life' and the brand's logo is engraved all over the case back. The limited edition will also the limited edition number engraved on the case back.

On the dial, we will find the Victorinox signature. On the limited edition we will also find the legend 'Limited Edition' at the 3 o'clock position and '125 Years' at the 9 o'clock position. The regular edition green dial will only the 'Jubilee Edition' at the 3 o'clock position.

What is interesting about the watch is the use of the Telemeter scale on the edge of the dial. Normally we see the use of a Tachymetre scale. The Tachymetre scale of course can be used to measure rate of production or speed of a vehicle over a given time period, e.g. km/h or mp/h.

The Telemeter scale was previously used by artillery observers. Basically this form of telemeter scale is an acoustic telemeter. Artillery observers use this scale to determine the distance between them and the enemy. What the observers would do is to record the time which elapses between the flash of the cannon and the sound of the shot. This is then translated to distance. Of course this would not work too well if the observers were the target of the cannons.

Today, the scale can be used to measure the distance to a storm by measuring the elapse time between the a bolt of lightning and the subsequent thunderclap. This elapse time is then translated to distance by the scale on the dial.
