FAQ
Learn
Essential knowledge for collectors and newcomers. Understand what you're buying before you buy it.
Every watch is powered by a movement — the engine inside. Mechanical movements are hand-assembled with hundreds of tiny parts, offering craftsmanship and heritage. Automatic (self-winding) movements use your wrist motion to stay powered. Quartz movements use a battery and crystal oscillator for unmatched accuracy. Spring Drive, pioneered by Grand Seiko, combines mechanical craftsmanship with electronic regulation for the smoothest sweep hand in horology.
Limited editions are produced in fixed quantities — sometimes as few as 50 pieces, sometimes several thousand. Brands like Rolex rarely announce production numbers, creating organic scarcity. True limited editions carry a unique serial number and often feature exclusive dial colors, materials, or complications not found in the standard catalog. They tend to hold or increase in value on the secondary market, making them both collectible and investment-worthy.
For sought-after models from Rolex, Patek Philippe, and Audemars Piguet, buying at retail requires building a relationship with an authorized dealer (AD). Visit regularly, express genuine interest, and consider purchasing other models first. For brands like Omega, Tudor, and Seiko, retail availability is generally better — especially online. Marketplaces like Chrono24 and WatchBox offer pre-owned and unworn pieces at market prices, often with buyer protections and authentication guarantees.
Water resistance ratings can be misleading. A watch rated to 30 meters isn't meant for swimming — it handles splashes only. 100 meters is suitable for recreational swimming. For actual diving, look for 200 meters or more with a unidirectional rotating bezel (ISO 6425 certified). Brands like Omega, Tudor, and Panerai build professional dive watches rated to 300m+. Always have gaskets checked annually and never operate the crown underwater.
