Review: Quality - The watch itself is fantastic. The built quality
Review: great watch so far :) - What a bargain ! great looking dive watch with helium valve . I use it in a medical hyperbaric chamber so haven't got it wet yet, but it keeps great time and is not to heavy. It appears to be well made and has a solid feel to it which I like. The luminosity is great and its easy to ready at night especially if its been in a bright place during the day. It claims to be 1000m waterproof I cant comment on that but I would be comfortable and will be recreational and tech diving with it ,

### ⭐⭐⭐⭐⭐ とても良い時計
*by ず***ょ on 5 June 2026*

重量はあるが、デザインとコストパフォーマンスに優れていて、素晴らしい。 価格の変動が激しい様なので、注意が必要。¥25000〜¥50000と変わるのはなぜか？セドリか？ 私は¥25000ほどで購入した。 ヘリウムエスケープバルブを装備する事で機能としては高級腕時計となんら変わらない性能を誇る。心臓部はセイコウの キャリパーが埋め込まれており、信頼性抜群。日差15〜20秒、とても正確に動いてくれる。32mmの風防は、やや小ささを感じるかもしれない。機械式時計のオーバーホール代より安い値段で買えるならこの時計は、ありだと思う
