Pilot Watch

About SoRa

Pilot watches have played a very important role in wrist watches' history. The impact of the First World War dramatically shifted public perceptions on the propriety of the man's wristwatch, and opened up a mass market in the post-war era. Wristwatches were found to be needed in the air as precise synchronization between different forces was required. The British War Department began issuing wristwatches to combatants since 1917.

It is said that one soldier in every four wears a wrist watch, and the other three mean to get one as soon as they can. By the end of the War, almost all enlisted men wore a wristwatch, and after they were demobilized, the fashion soon caught on - the British Horological Journal wrote in 1917 that "...the wristlet watch was little used by the sterner sex before the war, but now is seen on the wrist of nearly every man in uniform and of many men in civilian attire." It advanced the whole watch industry for at least 10 years!

Although pilot watches are so special in the watch family, it is surprised that they have never established a standard. So we decided to define a standard for pilot watches:

Size - A pilot watch is supposed to be read with ease, so it must have a big dial.

Large Crown - Pilots wear gloves when driving aircrafts, so the crown must be specially designed.

Precise Time Setting - Pilots need to set time precisely, even up to seconds, so good quality movements with hacking seconds function is a must.

Long Strap - Pilots may wear their watches on flight jackets' sleeves.

With the above standards as the baseline of design in mind, we came up with the perfect pilot watch, the SoRa.
