As often explained, homage watches are perfect material for modding. Who would swap the dial or the hands or the insert on a Rolex an Omega or a Panerai?
Seiko, Parnis, Bagelsport and others are more affordable tool watches.
From my experience and browsing through various website, and visiting those sellers offering dials or hands or else for mods (Harry Ng, Otto Frei, Jake Bourdeau, Raffles-Time, etc) this is my list of most common homage customization:
N°1: FFF (Fifty Five Fathoms)
N°2: BB (Black bay)
N°3: Submariner
N°4: Explorer
N°5: Sandwich (Luminor & Radiomir)
N°6: Flieger B'Uhren.
N°7: Seamaster
