SPB121JI is an international market release by Seiko, and replaced the popular SARB017. This model SADC091 is the same model produced for the Japanese market. Maybe that's why they called it a Limited Edition, the model number is exclusive to Japan, not the watch. **Q: The description says it’s a quartz watch the dial say automatic, love the green dial but I am confused 😐** A: Hello, This model is 100% automatic, mechanical movement. Best regards, GTJ **Q: I have small wrists 6 1/4 inch would this adjust enough to fit me?** A: Hello, The OEM strap will not fit your wrist. You'll have to find a shorter strap to use if you like this watch. Best regards, GTJ **Q: Does it have sapphire crystal?** A: Has a sapphire Chrystal, 6R35 movement and screw down crown ## Frequently Bought Together - Seiko Prospex Alpinist Limited Model SBDC091 Made in Japan - BARTON Elite Silicone Watch Bands - Quick Release - Choose Strap Color & Buckle Color (Stainless Steel, Black PVD or Gunmetal Grey) - 18mm, 20mm, 22mm & 24mm Watch Straps - Barton Quick Release - Top Grain Leather Watch Band Strap - Choice of Width - 16mm, 18mm, 19mm, 20mm, 21mm 22mm, 23mm or 24mm --- ## 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/371729909-seiko-prospex-alpinist-limited-model-spb121j1-made-in-japan-modern](https://www.desertcart.jp/products/371729909-seiko-prospex-alpinist-limited-model-spb121j1-made-in-japan-modern) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-10-27*
