JAPANESE NAVEL AVIATION CHRONO EST 700- FINAL 475

Solution

 

JAPANESE NAVEL AVIATION CHRONO

 

QUOTED WITH PARTS AFTER EXAMINATION
700.00

 

FINAL BILLED PRICE: 475.00

 

BEFORE YOU READ
LOOK AT THE DIAL BELOW
AND

THE MOVEMENT BELOW IT

 

IMG_8535.JPG (174847 bytes)

 

THE DIAL WAS ONCE THE EXACT COLOR OF OUR DIAL RESTORATION AND THE ILLUMINATION DOTS WERE USED.

 

THE HOUR, MINUTE, SUB-SECOND AND COUNTER HANDS ARE CORRECT - SEVERAL VARIATIONS WERE USED.

 

THE CENTER CHRONO-SECONDS HAND SHOULD WAS RED OR BLACK.

 

THE DESIGN OF HOUR & MINUTE HAND CORRECT.

 

WE VIEWED ONE SEIKOSHA NAVY AIR CHRONOGRAPH WITH 24 HR MARKERS THAT HAD AN OPEN DIAMOND TIP WITH CLOSED DIAMOND TAIL.

 

WE USED A SIMILAR BLACK SWEEPS AND AN ORIGINAL JAPANESE 24HR POCKET WATCH/TIMER DIAL IMPRINTER
TO IMPRINT THE RED 24 HOUR CHAPTER - WHICH PLACED THE "18" BELOW THE CENTER OF THE SUB-SECONDS
HAND RATHER THAN IN MIDDLE. OTHER THAN THAT, IT CAME OUT STUNNINGLY EXCACT!

 

 

 

JAPANESE WWII NAVEL AIR CHRONOGRAPH ON MILITARY WATCH FORUM
Seikosha Cased Longines Chronographs

 

Classic Seikosha Navy Air Chronograph, with 24hour markers.

 

BEFORE WWII THIS IS A COMMUNICATION BY   LONGINES COBNCERNING MR HATTORI AND SEIKOSHA:
"We have sent 1 movement alone on the 28th June 1941 to Messrs. Hattori, who were our agents in Japan at that time. It is a movement caliber 18.72 chronograph"

 

 

 

IMG_8537.JPG (163435 bytes)

 

OMG
LOOKS LIKE THIS MOVEMENT WAS ONCE
SUBMERGED HALF IN HALF OUT OF SALT WATER.
IT DEFINITIVELY EXPERIENCED A TOUGH TIME
TO SAY THE
LEAST

 

I RECEIVE HIGHER PRICE WHEN EVER I CAN SHOW WATCHES THAT  EXPERIENCED YEARS OF WAR FARE.

 

THUS WE ATTEMPT TO DUPLICATE WHAT WE SEE AND WHAT WE FIND ONLINE AND IN OUR MANY MILITARY RELATED BOOKS [450] WHEN WE RESTORE A WAR TEMPERED TIME PIECE.

 

THE GREATEST DIFFICULTY WAS THE COLUMN WHEEL MOVEMENT ABOVE IS IT'S TERRIBLE CONDITION. YET, AS TESTAMENT TO IT'S PRECISION PARTS, MATERIALS AND ASSEMBLY, THIS BABY STILL CHUGGED ALONG.

 

UNLIKE DISCOVERING A PRISTINE EXAMPLE THAT NEVER SAW THE WEAR AND TEAR OF COMBAT, THIS JAPANESE IMPERIAL NAVY PILOTS CHRONOGRAPH COME FROM AN ESTATE THAT HAS AN INCREDIBLE COLLECTION AND INVENTORY OF COMBAT WATCHES.

 

WATCHES THAT BELONGED TO SOLDIERS, AIRMEN, MEDICS, NURSES, DOCTORS AND OTHER MEN AND WOMAN THAT WERE IN THE THICK OF ACTION FROM WWI THROUGH VIETNAM.

 

THE MAJORITY CAME FROM BATTLE FIELDS OR PRISONERS OF WAR!

 

NOW, READ BELOW TO SEE THE BUTTERFLY THAT MORPHED FROM THE WORM!

 Kintaro Hattori

 

  • 881 -- Kintaro Hattori opens the watch and jewelry shop "K. Hattori" (Hattori Tokaiten in Japanese; currently named Seiko Holdings Corporation) in the Ginza area of Tokyo, Japan.

  • 1892 -- Seikosha is established in Tokyo as the clock manufacturing arm of K. Hattori.

  • 1917 -- K. Hattori becomes a company (K. Hattori & Co., Ltd.).

  • 1937 -- The watch production division of Seikosha is split off as Daini Seikosha Co., Ltd. ( "Daini" = "The Second" Seikosha).

  •  
    • 1942 -- Daiwa Kogyo, Ltd. is founded in Suwa, Nagano by Hisao Yamazaki.

    • 1943 -- Daini Seikosha establishes a factory in Suwa for manufacturing watches with Daiwa Kogyo.

 


 

FROM 1874 TO 1917,  JAPAN HAD SHED HER ANCIENT OUT-DATED WAYS AND MOVED WITH UNEXPECTED FORCE INTO THE MODERN WORLD. JAPAN  HAD BECOME A BUILDER OF HER OWN ARMAMENTS, SHIPS, PLANES AND HAD EVEN  IMPROVED UPON THE ADVANCEMENTS OF THE MODERNIZED WORLD. IN FACT, AFTER THE 1904-05 ANNIHILATION OF TWO VAUNTED AND POWERFUL RUSSIAN FLEETS, AS WELL AS THE DEFEAT OF RUSSIA' ARMY, SHE HAD BECOME A WELCOME TREATY PARTNER OF THE USA, BRITAIN AND THE WORLD AT LARGE.

 

BY 1917,  DAINI SEIKOSHA WAS SEEKING WESTERN TECHNOLOGY TO IMPROVE THEIR  CAPABILITIES TO PRODUCE MODERN WATCHES. THEY INVITED SWISS AND AMERICAN WATCH COMPANIES TO JAPAN. THEY DID WHAT THE JAPANESE DO BEST. UNDER THE BANNER OF POSSIBLE EXPORTS, THESE COMPANIES WOULD, IN FACT, TEACH THE JAPANESE WOW TO MAKE WATCHES THAT, BY THE 1950'S, WOULD COMPETE TOE TO TOE, WITH THE ENTIRE GLOBAL WATCH COMMUNITY.

 

 

 

AAAA-WALTHAM-JAPAN.jpg (91326 bytes)
1917

 

IN 1917, JAPAN HAD AGREEMENTS WITH THE MOST ADVANCED COMPANIES IN SWITZERLAND AND THE UNITED STATES. THE ABOVE ADD IS EXTREMELY IMPORTANT TO THIS OFFER AND ITS HISTORY.

 

MANY SEIKOSHA MILITARY WATCHES CONTAINED WALTHAM MOVEMENTS! IN ADDITION, SWISS TECHNOLOGY AND FINISHING TECHNIQUES CAN BE FOUND IN THE LIMITED ANTIQUE VINTAGE JAPANESE TIME PIECES AVAILABLE TODAY, SUCH AS THIS SEIKOSHA SEIKO TIME PIECE WITH SEIKOSHA MOVEMENT THAT HAS ALL THE CHARACTERISTICS OF A SWISS OR AMERICAN TIME PIECE OF THE DAY.

 

THE SEIKOSHA WATCH >
SEIKO > NATION + DELIKATA + OTHERS....

AFTER THE RUSSO-JAPANESE  WAR [1905], WITH JAPAN'S STUNNING VICTORY, JAPAN WAS ON THE MOVE. HER EMPIRE ON THE BUILD -MOTIVATED BY A GROWING RIGHT WING IMPERIAL MILITARY    WING - JAPAN, WITH FULL SUPPORT OF THE INTERNATIONAL COMMUNITY,   RECEIVED THE   RIGHT  TO "COLONIZE" KOREA.

 

IN REALITY, THE US-BRITISH AND FRENCH GOVERNMENTS SIMPLY HANDED OVER KOREA [1910] --WHICH HAD BEEN A RUSSIAN SEMI-COLONY--AS A "REWARD" OR THE LATE "SPOILS RESULTING FROM THE WAR.

 

IT WAS DURING THIS TIME THAT JAPAN SOUGHT WESTERN TECHNOLOGY IN A BID TO FURTHER WHAT WAS AN INCREDIBLE JOURNEY FROM A BACKWARDS TECHNOLOGY NATION OF 1875, TO A NATION THAT DESTROYED TWO RUSSIAN FLEETS IN 1905.

 

THE ONE AND ONLY POWERFUL SEIKOSHA COMPANY TRAVELED THE GLOBE ABSORBING ALL THE INNOVATIONS IN TIME KEEPING AND SOON BECAME THE MAIN WATCH AND CLOCK DRIVING AND PRODUCING FORCE IN JAPAN.

 

WITH MILITARY ACTIONS IN KOREA, CHINA, MANCHURIA AND OTHER PLACES, SEIKOSHA PRODUCED A HOST OF WATCHES WITH NAMES SUCH AS  "NATION" [ SIGNIFYING THE JAPANESE NATION] SEIKO [AS A MODEL LINE AND NOT NOT A BRAND YET],  DELIKATA AND OTHERS. THESE WATCHES WOULD BE WORN AND CHERISHED JAPANESE SOLDIERS.
