Best regards, GTJ ## Customer Reviews ### ⭐⭐⭐⭐⭐ Fantastic watch *by on Reviewed in Japan August 11, 2024* All the buying process was perfect I am very happy with the watch ### ⭐ 耐用年数 *by on Reviewed in Japan July 11, 2025* デザインや時計の持っている歴史、ストーリーに惹かれて正規店で４年前に購入しました。　購入当初は問題ありませんでしたが、昨年くらいから遅れが目立ち、日差で１５分という感じでした。　数か月前からは、止まる事が多くなりとても実用と言えない状況です。　特別問題のある使い方をしていたという感じはありません。　１５年前に買ったティソのオートマティックは元気に動いています。　アルピニストを購入後はほぼ毎日腕に巻いて使用していましたが、こんな状況なのでオーバーホールに出す見積を立てると４万円。　整備品の中古の方が安いかもしれません。もう一つの不満点は、皮ベルトです。汗をかく季節には皮ベルトをメタルバンドに取り換えて使っており、ほぼ秋冬の４か月程度しか皮では使っていません。２年目に遊革が取れてしまい、今年になってはバネ棒を差している部分の皮巻の接着が外れてしまいました。応急処置として接着剤で固定していますが、結構大事に使っていても実質１年半程度で使えなくなるというのは残念です。当初固い皮も使っているうちに馴染むということでしたが、皮が馴染む前に崩壊してしまいました。もしかすると大はずれを買ってしまったのかもしれませんが、時計自体はとても魅力的で気に入っているだけに非常にがっかりしています。 ### ⭐⭐⭐⭐⭐ Beautiful watch the band is a bit stiff *by on Reviewed in Canada June 4, 2025* Have been eyeing this for a year for my husband.Watch enthusiast!It was perfect. Just like the picture. There are some complaints about the band. He felt it was stiff but tried to soften it up but he will probably get another metal band.Beautiful watch. ## Frequently Bought Together - Seiko Prospex"Alpinist" Compass Green Dial Sapphire Glass Leather Watch SPB121J1 - Barton Quick Release - Top Grain Leather Watch Band Strap - Choice of Width - 16mm, 18mm, 19mm, 20mm, 21mm 22mm, 23mm or 24mm - SEIKO Automatic Watch for Men - Presage Cocktail Time - Patterned with Golden Numerals and Date Calendar, 50m Water-Resistant --- ## 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.kg/products/731956557-seiko-mens-prospex-automatic-watch-spb121j1-reverse-import](https://www.desertcart.kg/products/731956557-seiko-mens-prospex-automatic-watch-spb121j1-reverse-import) --- *Product available on Desertcart Kyrgyzstan* *Store origin: KG* *Last updated: 2026-06-24*
