耐用年数
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
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.

the real deal cant go wrong with seikos
This the real deal.. It is pricey, cant comment on the things i gave only 3 stars because I dont wear it much because it is so beautiful. A work of Art. Hey, it is a Seiko,,,it will last and can be repaired for 20 years after manufacture. And it will hold its value, I sent a 20 year old divers watch in to Seiko and they still had the parts for it, It puts Rolex's to shame. So does grand Seikos, I do own a gold Rolex and the case is all gold

Best In Class Seiko Watch
I am a watch collector and have a keen interest in classic watches. This is by far Seiko's best watch in a long time. This is classic yet elegant, a perfect balance between modern and retro style.The leather quality is very good, and the dial size is apt and would suit most wrists.The accuracy of the watch is pretty good, I would say, and I have been getting almost 70 hours of power reserve.You would not go wrong with this purchase.

Excellent watch, but not advisable to buy it on Amazon anymore
This was probably last good Seiko available online at a decent price. After March 2023, you won't be able to buy a good Seiko at a reasonable price on Amazon. There are importers who are charging twice (even e times of actual market price) the amount these days online. Please avoid online shopping to buy good watches.
