Citizen Promaster Eco-Drive Tsuno Chrono AV0104-06W Limited Edition

Citizen launched the limited-edition Promaster Land Eco-Drive Tsuno Chrono AV0104-06W to celebrate its rich watchmaking heritage, Eco-Drive 50th Anniversary. This remarkable creation merges historic vintage aesthetics with advanced modern technology. 

Horology enthusiasts instantly recognize its distinctive silhouette and iconic top-mounted control layout. Citizen draws direct inspiration from its classic 1973 Challenge Timer chronograph.

Watch collectors affectionately call this unique arrangement the bullhead design. Japanese watch culture uses the term tsuno to describe these horn-like top pushers. 

The brand pairs vintage motorsport spirit with clean contemporary craftsmanship. The watch embodies daring adventure while honoring five decades of light-powered innovation.

Specification

The case showcases a striking multi-piece construction crafted from solid stainless steel. Citizen applies warm yellow gold-tone ion plating across specific bezel and pusher surfaces. 

This two-tone finish provides dramatic contrast against the brushed silver-tone main body. Placing the primary winding crown and chronograph pushers at 12 o’clock ensures total wrist comfort. 

An auxiliary crown at 5 o’clock controls the internal alarm setting effortlessly. The robust case measures exactly 44.5mm in overall diameter. 

It features a substantial height with a total thickness of 15.3mm. The watch achieves an impressive water resistance rating of 200 meters. 

With this water resistance rating, you can safely swim, dive, or undertake intense water sports without worry. Citizen fits an anti-reflective spherical sapphire crystal directly over the dial surface. 

This premium glass provides exceptional scratch protection and pristine clarity under harsh light.

A rich brown leather strap anchors the heavy watch head comfortably to the wrist. Contrast stitching with cream-colored thread along the edges enhances the classic sports-car aesthetic. 

The strap fastens securely with a two-tone stainless steel push-button deployment clasp. 

Dial and Movement

The watch face presents a rich deep green background color. Citizen incorporates fine micro-textures across the dial plate to absorb light efficiently. 

Contrast sub-dials resemble dashboard gauges on vintage racing automobiles. Gold-outlined indices and hands carry luminous material for high visibility in dark conditions. 

An outer tachymeter scale ring with black background and white printing allows rapid speed calculations over fixed distances clearly. This watch has four subdials that sit at 3, 6, 9, and 12 o’clock.

Citizen powers this model with the in-house Eco-Drive quartz chronograph movement caliber E210. Watchmakers hand-assemble this complex engine to guarantee precise operational standards.

Light rays continuously recharge the internal power cell through the semi-transparent dial elements. Fully charged components run seamlessly for up to 8 months in absolute darkness.

The movement includes an instant flyback 1/5-second chronograph measuring elapsed time up to 12 hours and it has the accuracy ±15 seconds per month. 

An analog power reserve indicator displays remaining energy levels like an automotive fuel gauge. Additional features include a clear date window, instant mechanical reset, and a loud daily alarm.

Citizen limits worldwide production of this rare timepiece to just 5,000 pieces globally. Overall, the AV0104-06W stands as a triumphant fusion of heritage layout, bold styling, and sustainable engineering. 

Citizen Promaster Eco-Drive Tsuno Chrono AV0104-06W is priced at HK$10,380 or approximately US $1,320.
