The CA4590-81X bridges the gap between a rugged tool watch and a refined dress chronograph. Its standout feature is the deep sunray green dial, which shifts from a dark forest hue to a vibrant emerald depending on the light. While many chronographs feel cluttered, the CA4590 maintains a clean, "Modern Dress" look through its polished surfaces and integrated lug design, making it just as suitable for a suit as it is for a casual weekend.

• Anti-Reflective Sapphire Crystal:: The dial is protected by sapphire glass, the most scratch-resistant material used in watchmaking. The anti-reflective coating ensures the pink dial remains vivid and readable even under direct sunlight.
• Cyclops Date Magnifier:: A small magnifying "bubble" is placed over the date window at the 3 o’clock position. This iconic design element enhances legibility and adds a touch of classic sports-watch character.
• Integrated President-Style Bracelet:: The bracelet features rounded links (similar to the famous "President" style) that are integrated directly into the case. This design creates a seamless, high-end look and provides exceptional comfort on the wrist.
• Exhibition Case Back:: The rear of the watch features a transparent window, allowing you to observe the mechanical movement and the oscillating rotor as it winds the watch.
• Hacking Seconds Hand:: This movement includes a "hacking" feature, meaning the seconds hand stops when you pull out the crown. This allows for precise time synchronization down to the exact second.
