Size help

Size measurement

Please see below some useful information in order to give us your comfortable Ring Clock size. If you know your ring size that is perfect, but do not forget, a wider band needs a bigger size and the Ring Clock has a 14mm wide band so you may need a larger size than usual.

We advise the following techniques based on accuracy:

1) Rearing test 
The most accurate if you can try a 14mm wide ring in a jewelry shop. 
If you have a chance to go into a jewelry shop, where you can find a 14mm wide ring (12-15mm is good enough), just try it and ask the shop assistant about your correct size. (comment: it is not a common width size)

2) Reference database test 
Our test measurements show that if you have a X US size ring with the typical 4-5 mm width, then your Ring Clock (14mm wide) is around X+1 US size
For example: if your typical size is 10 US, then your best fit Ring Clock size:

  • 65% probability: 11 US size
  • 30% probability: 10,5 US size
  • 5% probability: 10 US size
