Mechanical elegance that never goes out of style. The NY4050-71L pays homage to classic Japanese watchmaking. Limited to 2,000 pieces worldwide, this automatic model stands out with its deep blue dial (inspired by lapis lazuli) and subtle gold accents. Equipped with sapphire crystal and the legendary self-winding caliber 8200, it is the perfect “lifetime” watch: no batteries, no planned obsolescence, and the beauty of seeing the machinery through its transparent case back.

💎 Sapphire Crystal: In this price range, many competitors use mineral crystal. Citizen uses sapphire here, ensuring that the dial looks pristine and scratch-free no matter what.

⚙️ Legendary Engine (Caliber 8200): One of the most robust automatic movements in history. It winds with the movement of your wrist, has a 42-hour power reserve, and supports manual winding. You can hear and feel the watch come alive.

🇯🇵 Limited Edition “Kinpekiju”: This is not a mass-produced watch. It is a short run of 2,000 units designed under the Japanese aesthetic concept of “Blue Sea and Golden Sun,” visible in the contrast of the blue dial with the gold rotor visible behind the back crystal.

🗓️ Double Calendar (Day-Date): Classic window at 3 o'clock with the day of the week and date. As it is a JDM base model, it is very likely that the day disc will come in English/Kanji (a highly sought-after geeky detail).

👔 Perfect Size (40mm): Eschews the trend for giant watches. With a diameter of 40.2mm and a thickness of only 10.7mm, it fits perfectly under a shirt cuff.

This watch is the answer to “Smartwatch fatigue”. There are no notifications here, just mechanical engineering.

The NY4050-71L is powered by the Miyota/Citizen 8200 caliber, a “workhorse” known for its extreme durability and ease of service. Unlike the older models in the 8 series, this modern version already includes Hacking (second hand stop) so you can synchronize the time to the exact second.

The “Kinpekiju” (金碧珠) design concept is subtle but beautiful: the blue dial has a sunburst finish that changes tone depending on the light, and the hands have a mixed finish (polished and matte) to maximize readability.

Note: This is a 5 BAR watch. Unlike the Promaster, this is a “Dress Watch.” It can withstand rain and hand washing, but it is not suitable for swimming. Treat it with the respect that a mechanical gem deserves.
