In the entry-level Swiss watch market, theCitroën DS-1 Big DateWith its excellent price/performance ratio and practical function configuration, it has become the focus of attention of many watch lovers. Can this piece, launched to commemorate the 60th anniversary of the DS series, stand out in the competitive market? Let's explore its real performance.
The balanced approach to design aesthetics
The Citroënne DS-1 Big Date has a uniquely balanced aesthetic in its design, with a diameter of 41 millimeters that has been carefully calculated to maintain the elegant proportions of a formal watch while ensuring comfort on the wrist. The case is made of stainless steel with a matte PVD coating on the black model and a gold PVD treatment on the gold model, each in its own color scheme. The black model with silver-colored faceted hour-markers displays an understated business-like aura, while the gold model with its midnight blue gradient dial creates a visual effect of luxury without being ostentatious. The case thickness is kept at 11.9 millimeters, a size that guarantees the stable operation of the movement and ensures that the watch can be easily slipped into a shirt cuff when worn. The curvature of the lugs is ergonomically designed to fit the wrist perfectly, so that no discomfort is caused even after prolonged wear. The overall design language is clean and uncluttered, without any unnecessary decorative elements, fully reflecting the design concept of ”form follows function”.

Practical innovation with a large calendar display
The most striking feature of this watch is its unique large date display. Unlike traditional single-window date displays, the DS-1 features two separate numerical dials for the tens and single digits, a design that makes reading the date more intuitive and clearer. The size of the digital display has been optimized for easy legibility even in low light conditions. The date switching mechanism is precise and reliable, enabling an instantaneous jump at midnight without any delay or lag. The large date window is carefully positioned at three o'clock on the dial to ensure a sense of visual balance without interfering with the display of other functions. The edges of the window are delicately handled, and the transition with the dial is natural and smooth. This practicality-first design idea makes this watch excellently practical in daily life and various occasions, especially for those users who need to check the date frequently.
Reliable guarantee of movement performance
The self-winding Powermatic caliber 80.651 is at the heart of the watch's reliable performance. The movement beats at a frequency of 21,600 vibrations per hour, which ensures precision while optimizing energy consumption. 80 hours of power reserve is a significant advantage of this caliber, which means that the watch will keep running even if it is not worn for the entire weekend, and will be ready for use on Monday. The movement's polished finish is not exactly luxurious, but the precision mechanics and attentive finishing details can be seen through the sapphire crystal caseback. The automatic tourbillon runs smoothly and winds satisfactorily. The movement is also equipped with a Nivachron antimagnetic hairspring, which is able to effectively resist the interference of daily magnetic fields, ensuring accurate timekeeping in an environment surrounded by cell phones, computers and other electronic devices. This technical prowess, which achieves outstanding performance within a limited cost, demonstrates the Citroënne brand's profound accumulation in movement manufacturing.

Comfort considerations for the wearing experience
When worn in practice, the Citroën DS-1 Big Date demonstrates excellent comfort and practicality. the 41mm diameter size is ideal for Asian male wrists, maintaining enough visual presence without looking overdone. The weight of the case is well-distributed, and the overall weight is kept within a comfortable range, so that prolonged wear will not cause fatigue. The straps are made of carefully selected materials and are matched with corresponding leather straps according to different styles, which are soft and breathable, and can quickly adapt to the wrist curve. The clasp is solid, reliable and easy to open and close, and its water-resistance to 100 meters far exceeds the standard for a dress watch, allowing it to be used in a variety of everyday situations, including washing hands, getting wet or even swimming. The anti-glare sapphire crystal ensures clear readability in all lighting conditions, and all these thoughtful details add up to an outstanding wearing experience.

In terms of workmanship, the polished quality of the case and the detailing of the dial are all of a fairly high standard, fully deserving of its price positioning.
