### ⭐⭐⭐⭐⭐ Love design and concept, brilliant flurescent hands and dial.
*by P***Y on 17 May 2025*

Love it. Great watch and no batteries required, what could be better. Bought for holidays as hands and numbers are flurescent so you can read it at night without putting light on.

### ⭐⭐⭐⭐⭐ Nice watch
*by J***S on 4 November 2024*

Nice watch, short strap. Had to buy a longer strap.

### ⭐⭐⭐⭐ Nice but not like the picture...
*by S***N on 21 June 2024*

Good value and comfortable but it is NOT a matt gunmetal grey like the picture. Actually the case is a gloss shiny black colour.... I nearly sent it back but decided to keep it as I already had the steel body Chandler version also.
