Introducing a historical timepiece made by Seiko: The Indicator 11A 14043N.
The 11A Indicator was Seiko’s first wristwatch with an automatic movement. In fact, it was the first wristwatch 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.
Since automatic watches were something new back then, the power reserve indicator on the 12 O'clock was added as a complication to show the amount of remaining power stored by the mainspring.
There were three variations to the 11a and this particular model is part of the second variant referenced as 14043, which employed Seiko’s very own S1 Diashock (anti-shock) system to the movement.
This is such an incredible collectible watch, we've rarely seen a two-tone variation which makes it rarer compared to the regular Gold or SS versions.

SOLD - Seiko 11a Indicator 14043N
This 14043N Seiko 11a Indicator is in great condition.
The watch appears to be fully original including the dial, hands, and crown. This particular model is nicknamed "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 small scratches and retains its sharp and beautiful faceted lug profile.
The dial is beautiful with no signs of scratches as it was preciously kept by its previous owner. The hands are crisp and have the period-correct and desirable “mountain” hands shape.
The movement is in great condition as the previous owner rarely used it.
