Amazing at first sight: the shocking moment of opening the package
When the exquisite watch box was slowly opened, I was deeply attracted by the texture of this VS Factory Seamaster 600 World Time watch. The 45.5 mm diameter shines in the sunlight, and the black zirconium dioxide ceramic case is finely brushed, exuding a low-key and luxurious luster. The most amazing thing is the Arctic perspective earth pattern in the center of the dial. Every continent outline and ocean texture is clearly visible, as if the entire earth is miniaturized in a square inch. The turquoise city ring contrasts sharply with the black dial, which is both fashionable and practical.

Wearing experience: the perfect balance of comfort and personality
Although the diameter of the watch reaches 45.5 mm, thanks to the carefully designed lugs, it feels comfortable to wear even on my 17 cm wrist. The ceramic case has just the right weight to neither look light nor burdensome to wear. Particularly worth mentioning is the black rubber strap that comes with the watch. The turquoise stitching not only echoes the color of the dial, but also adds a bit of fashion. The ceramic folding clasp opens and closes smoothly, perfectly solving the difficult-to-operate pain points of traditional diving clasps.

World time function: the best companion for global travelers
What surprised me most about this watch was its precise world time function. The local time can be easily adjusted through the crown, and the time zone display of 24 major cities in the world is perfectly synchronized with the GMT hand. I specifically tested the time difference adjustment from Beijing to New York. The date display will automatically follow the time zone change. This detail processing is even more user-friendly than some genuine watches. The 24-hour scale ring on the outside of the inner dial adopts a two-color design, and the day and night display is clear at a glance, which is great news for business people who often need to make calls across time zones.

Craftsmanship details: The devil is in the details
Observe carefully with a magnifying glass, every detail can stand scrutiny:
- The honeycomb texture on the dial is created using laser ablation technology, giving it a full three-dimensional feel.
- The diving scale on the ceramic bezel is clear and sharp, and the damping feels just right when turning.
- “Seamaster” is finely printed with no burrs on the edges
- The luminous coating is even and full, and can continue to glow for 6-8 hours in dark places.
- Although the 8938 movement with a back-through design is not as refined as the original version, the Geneva pattern polishing is quite good.



Actual test performance: not just a “vase”
After a week of daily wearing testing:
- Travel time accuracy: daily average error +3 seconds, reaching the observatory certification level
- Waterproof performance: tested swimming and snorkeling without any pressure (but it is recommended not to operate the crown underwater)
- Durability: The ceramic case has excellent scratch resistance and no obvious wear and tear during daily wear.
- Comfort: The rubber strap becomes softer the longer you wear it, and it will not feel stuffy when worn for a long time.
