What would you change? The gold watch in the bottom right is an Accutron 214 that belonged to my grandfather. So that one stays.
Others from left corner down:
Tudor Black Bay ETA Steinhart Ocean Vintage Red 39 Seiko SKX009 Breitling Blackbird Glycine Airman 18 Dan Henry 1964 Seiko Presage Cocktail Time Seiko SARB033 Vintage Omega Seamaster
My steinharts are nice (I have two of them) but my Pelagos 39 blows them out of th water (as it should, its over 6x the price of a Steinhart)
