Longines Conquest AHP

ETA 205.911

What an unusual name: Armpowered High Precision. When I bought it, I had imagined (without having done any research) that it was 'high precision' in the same sense that the Longines Conquest VHP was 'high precision'. That is to say, thermocompensated and accurate to 10 SPY. I quickly discovered I was wrong. This watch is not thermocompensated and has the accuracy of any ordinary quartz watch. It is, however, an autoquartz. That ticks a box in the collection, at least.

Longines AHP

As a reminder to myself, whilst this watch is not 'HAQ', the technical documents do mention that it has a 2-minute inhibition period. It is also recommended that the watch be stored with the crown in position 3, to conserve power.

Some details about this watch are currently missing, as it is kept several thousand miles away, in the UK.
