Review: Not efficient - Loss of money
Review: 腕時計のベルト調整等に問題あり - ベルトの長さの調整用に接続部品を外すちょっとした工具が付属されてはいましたが、ベルトのピンを一つ何とかカンとか外したところ、塗装が変にこびりついていて、他は外れず苦労しています。また、本体の裏側にある電池交換の際に開け閉めするカバーにはネジがなく、どうやってとめているのか（？）開けるのにも苦労しそうです。 デザインは斬新ですが、買わない方が良いかも・・・。

## Questions & Answers

**Q: Can i purchase extra links for this watch?**
A: Not sure..I suppose I'd just order an extra watch to cannibalize links from.

**Q: How do you reset the seconds when I hit the second button it does nothing?**
A: Hold both buttons down then when it starts flashing hit them again and then adjust the seconds

**Q: So this watch only displays time in a 12hr format not a 24hr ?? Why do I see 22 55 wouldn't that be 10:55?**
A: You can set the 12/24hr format, You do it at in time setting mode. You just keep clicking through the hour and it goes past am/pm to military.

**Q: The link does not come off?**
A: The link(s) do come off. There was a tool enclosed with the watch. It pushes the pun out to remove the link. You should have instructions included in the box. I hope this helps you

### ⭐ 腕時計のベルト調整等に問題あり
*by 鮭***郎 on 30 September 2024*

ベルトの長さの調整用に接続部品を外すちょっとした工具が付属されてはいましたが、ベルトのピンを一つ何とかカンとか外したところ、塗装が変にこびりついていて、他は外れず苦労しています。また、本体の裏側にある電池交換の際に開け閉めするカバーにはネジがなく、どうやってとめているのか（？）開けるのにも苦労しそうです。 デザインは斬新ですが、買わない方が良いかも・・・。

### ⭐⭐⭐ 中学生なら喜びそう♪
*by の***ま on 8 September 2024*

シンプルで変わったデザインに惹かれて購入してみました。 画像では本体カラーは「ブラック」ですが、 実際は「ガンメタリック」でした。 塗装も気泡が入っていたり、右側のボタンの 押し具合も微妙な感じ・・・（＾＾；） 青色のLEDも画像よりも薄い感じです。 変わったデザインですので、 大人よりも小・中学生くらいの子なら 喜びそうな時計です♪
