I also purchased an earbud with a microphone, and am having more success obtaining reasonably accurate results, keeping in mind that this is an inexpensive hobbyists tool rather than a professional tool costing hundreds of dollars. After purchasing a demagnetizer, my watch now appears to be back to normal. Even worse, when using the built in microphone of my iPad, it magnetized my watch, causing a watch that typically runs at -1.1 sec./day to gain about 40 seconds in a day, and then to run about 5 sec./day slow. The fourth one is a very rare type with square markers at 3, 6, 9 and 12 and a graded dial.Initially, I had far more failures than successes in trying to obtain good data from this app. These also come with a number of different outer bezels both plain and more elaborate with fluted design. The main change - other than those mentioned already - seems to be better efficiency in the day wheel function.
The 6206 of course represented a significant price cut to JPY 12,500 from the JPY 15,000 of the 400 series, together with the Marvel it is probably the one with the most versions. It was made to be an affordable watch for the normal man, the train bound commuter in Japanese society during the mid-60s. These watches are still quality watches but are merely produced in a very cost-efficient manner, the Weekdater complication was even dropped in later versions. The excessive 35-jewel count of the 6218, and likewise that of the 57GS and 62GS, are all examples of the solution to the datewheel shake fall problem.īelow the date wheel three jewels were added to keep it balanced and stabilized.

It could be comfortably compared to the 57GS manual wind Self-Dater of 1963, and was well before the launch of the first automatic 62GS in 1967. Generally speaking however this Seikomatic Weekdater was already Grand Seiko material. Styling differences can be easily seen on the dial design, the presence or absence of the (applied) Gyro symbol or the little star just above the six oclock marker or the framed-unframed weekdate window. The weekdaters used the 4006206 movement and evolved into the first chronometer Grand Seikos. That in turn evolved into the majestic 39 jewel 395 Self Dater 50 Proof of 1963. The mentioned date complication first appeared in the 24 jewel 394 Seikomatic Selfdater of 1962, later renamed as caliber 6205. This Seiko invention from 1959 improved winding efficiency, by transferring all oscillating movements of the moving weight - both clockwise and counterclockwise - to the main spring thereby reducing the time needed to fully wind the spring. Rather than the magic lever used in the automatic only 62 caliber, this winding mechanism incorporated the very practical and effective inversion roller system that allowed the watch to be manually wound via the crown.īusiness or Seikomatic It was difficult to choose The first Seikomatic appeared in 1960, austere in design and function, but providing the starting point for a luxury product line that culminated into the early Grand Seiko.įeatures included waterproof cases, more or less mysterious complications like calendar, slimdate, selfdater and of course an automatic movement fitted with the brilliant magic lever invention, which uses pawls (consider them paws actually) rather than direct gearing between the oscillating rotor and the barrel.
