This double calendar timepiece is based on the design of Longines Master Collection by Longines, featuring classic dress-watch aesthetics combined with practical calendar functions.
It is equipped with an Asia ETA 2836-2 automatic movement, corresponding to the original Cal. L636.5 specification, providing stable and reliable mechanical performance.
The dial showcases a refined barley-grain (wheat) texture, carefully adjusted through repeated refinements to match the original visual depth, grain thickness, and overall tonal finish for a highly authentic appearance.
All components are produced using original watch as reference molds, with parts designed for compatibility and interchangeability with the original model. The case size is 38.5mm by 11mm, maintaining a balanced and elegant proportion.
The bracelet undergoes secondary precision polishing, giving the edges a smoother and more integrated finish, enhancing wearing comfort and overall refinement.
Overall, this model emphasizes double calendar functionality, classic Master Collection styling, refined dial texture, and balanced case proportions.
