The movement used is the Dandong 7750 caliber converted into the original CAL.69355 caliber. Thickness, all unit data and layout, balance position and function usage; It matches perfectly in every respect, it's perfect.
Dial and Hand Details
The sapphire crystal is treated with the anti-reflective blue coating common to the latest edition of YL Factory's Portugieser Chronograph; This strengthens both the texture and the anti-reflection feature. The green dial is not a bright green like meadow green, but a completely remixed metallic green; In this respect, it is much closer to the original color tone. Radial pattern processing makes this green even more eye-catching and striking. Silver Arabic numerals are used as hour markers on the dial surface, with dot details interspersed between them; The inclined part on the outer frame forms the minute scale. A three-hand design was chosen in the middle: a hammered (dauphine) hour hand, a minute hand and a chronograph seconds hand. In addition, there is a 30-minute chronograph counter at 12 o'clock and a small seconds counter at 6 o'clock.
Side surfaces are processed by brushing; This reduces the damage that unexpected scratches can cause to the watch's appearance. This model is a chronograph watch; It has three crowns. The ones on the right and left serve as chronograph buttons and stop and reset buttons. The crown in the middle is used for time setting and winding function.
Strap, Buckle and Comfort
