An iKrono Smileday watch by Alain Silberstein, numbered 60 of 500, is estimated to make £3,200-4,200 ($5,482-7,195) at Fellows in Birmingham, UK on July 21.

The iKrono Smileday is one of only 500 ever made

The design is typical of architect Silberstein's avant garde approach to watch making, which combines the playful with the utilitarian - evident here in his replacement of the days of the week with expressive faces.

We have this Longines Men's Olympic Series watch available.
