Hand wind watch with 36000 hi beats
With 36000 bph, it means the movement in this watch "beats" 36,000 times per hour, or ticks 10 times per second (When this watch was made, Rolex's best movement beat 19,800 times per hour or 5.5 times per second, and to this day their best tops out at 28,800 or 8 times per second). This provides for a sweeping second hand so smooth, it looks like an old fashion classroom electric wall clock and ticks so fast it sounds like a toy machine gun. One of the most beautiful things on Lord Marvel is its curved dial making it a classic!
The 1964 Grand Seiko Chronometer (caliber 430 / 43999) is a landmark timepiece, introduced by Seiko during the year of the 18th Olympiad in Tokyo. Seiko timed the games flawlessly, and their success at the 1964 Olympic Games gave Seiko international respect and credibility.
In 1964 Seiko entered the Astronomical Observatory Chronometer Concourse in Neuchatel, Switzerland for the first time and secured a 144th and 153rd place amongst the worlds finest chronometers. In 1967, SEIKO secured 4th, 5th, 7th, 8th and 12th place in the Chronometer Concours, winning 2nd and 3rd place in 1968. In 1969, with the advent of quartz movements, the Observatory contests of Neuchatel ended. During the early 1960s Seiko displayed the 'Chronometer' name on selected, precision watches which had passed the in-house Seiko chronometer standard testing, the equivalent of the BO (Basel Observatory) Chronometer standard, but stopped displaying the ‘Chronometer’ designation in 1966 due to the lack of independent CICC Certification facilities in Japan. Today, precision Seiko watches displaying the simple ‘Chronometer’ designation are a rarity sought after by collectors, and perfectly reflect Seiko’s “finest decade”.
Caliber 430 (43999) Chronometer movement
Concealed below the subdued, pearl silver sunburst dial with faceted, applied steel markers and the modest legend: "SEIKO Chronometer, Grand Seiko, Diashock 35 Jewels" beats a chronometer-grade movement defined by hand-selected and impeccably finished components, fine regulator, self-compensating hairspring, generous jeweling and large balance.
Many of the new collectors often get confused with regards to the 43999 and 5722-9990. To facilitate your understanding, I have put together a comparison
