Many CITIZEN L models are inspired by shapes and light found in nature, and this model is themed around 'morning dew.' The three diamonds on the case move smoothly along the curve of the case, and the indexes are scattered across the dial, creating a story that evokes scenes from nature even for those who know nothing about the watch. Looking at the parts, despite the many asymmetrical elements—such as the dial pattern, index arrangement, crown position, and case shape—each is balanced in its placement, so there is no sense of discomfort or difficulty in wearing it. The asymmetrical design brings a rhythm and movement reminiscent of the vitality of nature, making you feel a relaxed, natural flow of time rather than a uniform one. Although the watch uses many diamonds and has a jewelry-like feel, the arrangement of the indexes and the spacing between the case and band give it an airy look, making it suitable for everyday wear as well.
While the dial and case feature decorative elements like diamonds and the reflective light of white mother-of-pearl, the airy spaces where the diamonds move and the gaps in the band give it a lightness that would suit casual outfits.
The design gives the impression of an extra frame around the case. The three diamonds move side to side—a structure not found in typical watches—resulting in a thin, wrist-friendly shape. The case features finely angled surfaces throughout, which not only create beautiful reflections of light but also make the watch appear visually thinner.
Diamonds move smoothly from side to side. The moving parts, in addition to the hands, are refreshing, and even when you have no reason to check the time, you’ll find yourself tilting your wrist to watch the diamonds, captivated by their charm.
The design concept of 'morning dew' is strongly felt. Diamonds and applied indexes are arranged to sparkle as if spilling along the radiating dial pattern, giving an organic beauty. Although they appear to be randomly placed, in fact, each index position is set with either an applied index or a diamond.
The rounded, glossy surface and the organic shape reminiscent of a flower bud match the case design. The crown has no sharp edges and feels pleasant to the touch.
The outer ring and the inner watch body are made as separate parts. The case is slightly larger, but the open spaces where the diamonds are set and the finely angled surfaces throughout make the watch look smaller and slimmer.
Both the outer and inner links have no cut surfaces, featuring a soft curved shape. This matches the atmosphere of the case and dial, feels comfortable on the skin, and is equipped with a double push-button clasp.
ENGINEER'S EYE
Moving Diamond
The top priority challenge for this model was how to realize the design concept of “a diamond that moves within a gap whose width changes.” Starting from hand-drawn sketch ideation, we moved to 3D drawings, verified feasibility with a 3D printer, and then validated product feasibility using stainless steel samples machined on a five-axis processing machine.
A motivated team gathered and conducted repeated studies to realize the Moving Diamond. Since it was a mechanism we were adopting for the first time, we examined the weaknesses of this structure, defined items for reliability testing, and achieved smooth diamond movement.
For the shell dial pattern, we experimented with etchant concentration, time, and mask patterns in various combinations, exploring the optimal processing method. Because we incorporated many new attempts, it took time to perform reliability tests and address issues, and we received extensive cooperation from all related parties, including adjustments to the release schedule.
I still vividly remember the excitement in the meeting room when we reported that this model had finally passed its tests.
