The popular style "Panda" timing style, there are still quite a few watch friends who like it.
After repeated understanding of the San Martin Panda BB Chronograph Retro Men Watch movement, the small plate at 3/9 o’clock and the mechanical movement with the core on the same horizontal line are indeed relatively few choices. In the end, I decided to choose the ST19 movement. This is the first time I have used this watch in the past 5 years. movement. This ST19 series movement is still used in many domestic and foreign watch brands, and the overall evaluation is quite satisfactory. I also specifically asked the movement factory that this movement is unstable and can be replaced directly by the movement factory. We will observe the running time more carefully before assembling, and we will replace it directly if it does not meet the standard.
Because the San Martin Panda BB Chronograph Retro Men Watch movement is a manual mechanical movement, and the crown is a push-pull structure, we have mature diving watch structure experience, and the push-pull structure is still made into a 100m waterproof level (you can wear it for swimming), so watch friends can rest assured in terms of waterproofing.
Let’s briefly talk about the San Martin Panda BB Chronograph diameter and thickness. Many watch friends recommend 38-39 sizes. This one has no diving chronograph. The upper lap is a dead lap structure, so it can’t be made too thick. The large bevel makes the position of the movement the thinnest thickness of about 13mm. I personally think that 40-41 is more ideal for the design of this San Martin Panda BB Chronograph thickness and diameter ratio, so the diameter of the case is designed to be 40mm, and the diameter of the bezel is designed to be 41mm.
Let me share with you the details of some changes in the watch:
1. San Martin Panda BB Chronograph Case aspect: The movement adopts the Seagull ST1901 manual chronograph movement, with a thickness of about 13mm; the side scale of the case is modified, the middle case is thinned, and the upper ring is thickened. I personally feel that the side scale is more coordinated; the lugs are bent downward The radian is increased, which I personally think is more coordinated; polishing the case body is a polishing process, and we changed it to a straightening sand process.
2. San Martin Panda BB Chronograph In terms of hands: refer to the Tudor snowflake needle as a whole, the 3 and 9 small hands are covered with a flat-top second cap (the common technique of GS), and the luminous window is filled with retro yellow luminous.
3. San Martin Panda BB Chronograph Dial: the overall reference to the Tudor style, the color tone is changed to a retro style, and the time scale luminous also has a retro effect.
