Oops, sorry for the typo error!
Should have read 16610.
The older version, was very comfy to wear, and sat lower down on my wrist, but the lume was quite poor and as the years went by, became less.
As someone who tends to wear their watches virtually 24/7 being able to read the time during the night is important to me.
I can't say that the 1mm, which we know is not quite that, has made very little difference to me.
