Packaging is lesser quality that my Japanese assembled Seikos. On the plus side a user manual was included and it says the movement was made in Japan (4R36). **Q: Does this watch come with a stamped warranty card?** A: Yes **Q: Does this watch come with a brand new battery? Just purchased it but it seems to stop working totally and if I put it on seems to start working again.** A: You bought an Automatic the watch has no battery at all it works by the movement of you. The watch has a weight on the inside that rock back and forth that keeps the mainspring wound. You have to ware the watch for it to keep time. On a full day it should last around 30hr before you need to put it back on. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/368757181-seiko-srpg18-prospex-mens-watch-brown-42-4mm-stainless-steel](https://www.desertcart.jp/products/368757181-seiko-srpg18-prospex-mens-watch-brown-42-4mm-stainless-steel) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-11-15*
