So many people have armoires with 7 drawers. I remember asking the furniture store employee why is it 7 drawers. She told me it was one for each day of the week! So you can't go beyond 30 since there are only 30 days in a month! That's very true! Back to the more "serious" topic... A minimum critical mass of watches is a good idea... But... let's say you have 15 watches. Could you go down to 8? And some of those 8 pieces could be truly special pieces. Do you aspire to own a special example of watchmaking? Like a Kari Voutilainen or something else that's very special? Let's assume that the total "value" of your collection remains about the same... Would that be in the cards?
