Pilot watches

During the Second World War further technological advancements to military watches were made.

In Aviation “Pilot” or “Navigator” watches were born. Pilot watches were developed due to the need in Aviation for the precise measurement of seconds, to achieve this, watches were fitted with a “seconds bezel”.

Split second timing is crucial for military watches, especially in aviation since a deviation of only a few seconds could lead to huge navigational errors. So the seconds bezel was an important addition. It aided in navigation because the pilot could use this bezel to synchronize with the correct reference time before taking off. It was also useful for making adjustments to radio time signals whilst in flight so that “chronometer errors” and consequently navigational errors could be avoided.

The Longines “Weems” pictured above released in 1929, was the first wristwatch specifically designed for aeronautical navigation. Named Weems after Professor Philip Weems of the US Naval Academy with whom Longines collaborated with on the watch’s design. Later in 1932 Longines would team up with famous aviator Charles Lindbergh to create their further improved “Hour Angle” watch (right)

lepo... mozda bi zeleo da angazujem moju sestru da prevede ovo kao strucni prevodilac i zaradi nesto para...

Pilot satova

Tijekom Drugog svjetskog rata na daljnji tehnološki napredak vojnih satova su.

U zrakoplovstvu "Pilot" ili "navigator" satovi su rođeni. Pilot satovi razvijeni su zbog potrebe u zrakoplovstvu za precizno mjerenje u sekundi, kako bi se to postiglo, satovi su opremljeni s "sekundi oštrica".

Split drugi vrijeme od presudne je važnosti za vojne satove, pogotovo u zrakoplovstvu jer odstupanje od samo nekoliko sekundi može dovesti do velikih navigacijskih pogrešaka. Tako sekundi oštrica je važan dodatak. Ona pomaže u plovidbi, jer je pilot mogao koristiti ovaj okvir za usklađivanje s odgovarajućim referentnim vremena prije nego uzimajući off. To je također koristan za izradu prilagodbe vrijeme radio signale dok je automobil u letu tako da je "kronometar pogrešaka", a time i navigacijske pogreške mogu izbjeći.

izvor Longines

The Longines "Weems" na slici gore objavljen u 1929, bio je prvi ručni sat posebno dizajniran za zrakoplovnu navigaciju. Ime je dobio nakon što je profesor Philip Weems Weems u SAD Mornaričke akademije s kojima su surađivali s Longines na watch dizajna. Kasnije u 1932 Longines će udružiti s poznatim Aviator Charles Lindbergh stvoriti svoj dodatno poboljšati "čas kutom" Watch (desno)
