1978 Rolex Submariner Ref.1680
サブマリーナーに初めてデイト機能が搭載されて、デイト表示を装備したロレックス最初のダイバーズになります。
防水性を高めたトリプロックリューズを採用したのがこのモデルからです。ムーブメントには、20年以上に渡ってスポーツモデル全般に採用されていたcal.1570が採用されました。後期型はリューズを引くと秒針が止まるハック機能が付いています。

この時計は既に修理、分解掃除が終わっていますのでご注文後、軽清掃のみで直ぐにお渡し可能です。修理方法については春日々和（オーナーブログ）をご覧下さい。

ブレスを含む全体の経年擦り傷ですが、軽くしか研磨していません。ご要望であればご注文後、研磨致します。　外装は磨きすぎると、強度・防水精度が下がる他、ダイヤルとの経年も合わなくなったりで時計にとって何一つ良いことはありません。あまりお薦めしません。
