Unlike what the others said, I do wear a different watch everyday.
Hence, I have 6 autos and another last (hopefully) auto incoming. My watch tend to be different than each other and trying to fit in the theme fo dress, diver, pilot, choronograph, gmt and more. Also, I only stick to one model per brand, thus curbing the itch and saving my wallet in the process.
But the N+1 theory seems right too coz just as I was about to end my journy with the Ventura incoming, I saw the Bulova lunar pilot on carousell.....hmmm....ahhaah....
Enjoy the suffering, guys!!
