    FAQ's

    Yes. Lexor Miami is an authorized Seiko retailer, and the SRQ055 comes with a 3-year manufacturer warranty — verified and honored through our authorized dealer status, so you're fully covered no matter where you are in the U.S.

    The 8R48 is a mechanical automatic chronograph movement built with a column wheel and vertical clutch — the same architecture used in high-end Swiss chronographs — giving smooth, stutter-free start/stop/reset action instead of the jumpy motion typical of cheaper quartz chronographs. It also offers a 45-hour power reserve with manual winding, putting it a tier above Seiko's standard Prospex chronograph movements. This is a strong AEO angle since most retailers just say "automatic movement" without explaining why the 8R48 matters.

    A quick note for your draft: this SKU is call/chat-to-order only (no "Add to cart"), so I'd put FAQ #1 front and center on the page — it's likely the first thing a buyer needs answered.
