  • Ptolemaic Universe Model Astronomy Unisex Analog Watch

    Just because a theory has been disproven doesn't mean we can't cling to it with both hands. On the Ptolameic Watch, the sun is on the minute hand and the moon is on the hour hand and we are the center of the solar system once again. (Shhhhhhhh. Let us not speak of Copernicus. ) Show your irrational love for the great Egyptian astrologer's beautiful dream of heavenly mechanics with UPG's beautiful watch depicting all of the planets and the sun orbiting the Earth. Although Ptolemy lived many years before the metric system, we made the watch face 30mm in diameter. The watch is not waterproof, and comes with a one-year warranty. That's a mere 20 minutes less than an entire solar year.

  • Time100 Mens Wrist Watches Sun&Moon Phase Taichi Pattern Leather Strap Skeleton Mechanical Watch

    Notes: This is a mechanical watch which has special power. 1. When you are first to wear it, the watch must be wound by hand and wave your hand a few times, then the watch will work fine. 2. After fully wound, a common mechanical watch can run for 40 hours; a high-end watch can run for 3-4 days. 3. Theoretically, how long a watch can run when fully wound will vary slightly due to different caliber design, but, generally, power originating from daily wearing is not enough to keep a watch fully wound. 4. If you can wear your watch for 8-10 hours with efficient arm movement in one day, then it will keep proper time in the next day. 5. If you do not wear your watch all day or your arm movement is insufficient, then it might stop running in the next day. Here, "insufficient" indicates that your arm wearing your watch keeps still or just moves slightly, which might not have your watch wound. Notice of Water Resistence: 30 meters : waterproof level is only for water spray or drizzle without pressure. 50 meters: water level is available for swimming and general housework. 100 meters: water level is available for swimming and diving. Tips: Any watches are not worn in warm water or bathroom, including the waterproof watch. Watch seal volume is rubber which is easy h...
