The aperture of a watch refers to a small opening on a dial that reveals certain information, such as date, day, month, power reserve, or moon phase. Probably the most well known example is the Rolex cyclops which magnifies the day of the month aperture.

Swiss Watch Boutique very nice. Great post! Buying Swiss watches is definitely a great investment.
Is small aperture/long exposure a way to increase DoF? If so, then I’ll try it too, when the light returns to the Northeast U.S.
