The 11A Indicator was Seiko’s first wrist watch with an automatic movement. In fact it was the first wrist watch produced by a Japanese manufacturer to utilize an automatic movement. The 11A was produced by Seiko's Kameido factory and was released in late 1955. The automatic movement used in the 11a was based on a Swiss movement - the A. Schild caliber 1382. There were three variations to the 11a. The first was the ref 14015 introduced in 1955 which used a Nivaflex mainspring and hence was not a fully in house movement. This movement originally used a Swiss imported E-1 and R antishock system. The final batches of the 14015 had Seiko's in house S2 diashock system. The second variant was the reference 14043, which now employed Seiko’s very own S1 diashock (anti shock) system to the movement. The final execution, was the 14060, which had a larger 37mm case size and the movement fitted with an improved S2 diashock protection system.
Overall, this 14015 Seiko 11a indicator is in really nice condition. Everything of this watch appears original and we should note that this is a rare 3rd execution of the 14015 variant nicknamed the "shirokin" (白金) or white/gold by Japanese collectors, due to its stainless steel case fitted with gold index and hands. The stainless steel case has a few nicks and scratches but retains its sharp and beautiful faceleted lug profile. The dial has aged well and is in great condition with a visible scratch at the center of the dial above the "21 jewels" text. There are tiny spottings throughout the dial which is common on these cream colored dials from this era.The hands are crisp and is the period correct and desirable “mountain” hands shape. The movement was last serviced in November 2014 at which point the previous owner rarely used the watch. It is currently running at +36.2 sec/day at the upright position. We can service this watch for an additional fee if the purchaser wishes to do so (JPY 11,000).
This watch comes with a new alligator beige strap shown on the second picture
