本日もご覧いただきありがとうございます！販売春日店冨永です🎓

6月になりました今年も梅雨の時期ですね、もう九州南部は梅雨入りしているそうです

そんな雨の時期に必要な腕時計機能と言えば「防水」です

腕時計が普及してきてから問題となったのが機械部分に水が入る事で起こるサビの問題でした

別に雨でなくとも手洗いや汗でも時計に水は入ってしまいます

そんな昔画期的な構造の時計ケースが世に出ました

オイスターケース

オイスターとは牡蠣の事で殻のように頑丈で水を通さないことからこの名がつけられました

この世界初の完全防水ケースを1926年に開発したのがロレックスです

そんなロレックスの中でも最も防水性が高いシードゥェラーはなんと

3900m防水です

3900m!!

もはや潜水艦です・・・・

ケースサイドに付いている丸い溝はエスケープバルブと言って

飽和潜水と言う特殊な潜水を行う際に時計を守るために付いているのですが

常人には使うことは無さそうな機能ですね😶

しかし防水機能にはまだ上があります

15000m 防水！

誰が付けると？

It's June, and it's the rainy season again this year, and I hear that the rainy season has already started in southern Kyushu.

The watch function that is necessary during such rainy season is “waterproof”!

Since wristwatches became popular, one of the problems that arose was the problem of rust caused by water entering the mechanical parts of the watch.

Even if it is not rain, water can get into a watch by washing hands or sweating.

In such a time, a revolutionary watch case with a revolutionary structure was introduced to the world.

Oyster case

Oyster is an oyster, so named because it is as tough as its shell and impervious to water.

Rolex developed the world's first completely waterproof case in 1926.

The Sea-Dweller, the most waterproof Rolex watch, is water resistant to 3900m!

It is water resistant to 3900m!

3900m!

It's a submarine. ・・・・

The round groove on the side of the case is called an escape valve.

The round grooves on the side of the case are escape valves to protect the watch during a special type of diving called saturation diving.

It's a feature that normal people don't seem to use 😶.

But there is more to water resistance

Omega “Seamaster Planet Ocean Ultra Deep” 

15000m water resistant!

Who would wear it?
