Paul Newman dial on a yellow gold case with black ground and gold-toned sub-dial surrounds and hour markers, named for the John Player Special-sponsored Lotus F1 team livery of the 1970s. The 14k yellow gold [[Reference:6241|6241]] is the most populous JPS host (fewer than 400 produced, North American market). | ||
'''Lemon dial.''' Yellow lacquer full-dial finish fitted to rare gold-case 6263 and 6265 examples. Per Revolution's 2017 Ridley bench dissection, gold-case Paul Newman Daytonas are always the Lemon variant, with rare RCO exceptions. | '''Lemon dial.'''

'''Albino 6263.''' White-on-white monochromatic dial | '''Albino 6263.''' White-on-white monochromatic dial: silver sub-dials on a white base, bearing only "Rolex Oyster Cosmograph" without the standard "Daytona" wording. Three known examples. Authenticity is contested. Hodinkee (Clymer 2013) treats it as a factory Rolex variant; Perezcope (2025) reads it as a 1990s Tom Bolt construction. See [[Reference:6263|6263]]. | ||

Disputed dial configuration presented at Phillips Daytona Ultimatum 2018 as the earliest Paul Newman prototype. Perezcope's 2022 dossier reads the dial as a late-1990s construction off a 6238 donor, citing the April 1998 ''Orologi & Market''. Both positions on record. See [[Reference:6240|6240]]. | ||

Zenith-era dial where the varnish over the silver sub-dial rings turns brown. Named for Osvaldo Patrizzi. Window sits in the mid-1990s by most accounts. Genuine Patrizzi ageing usually runs uneven across the three sub-dials; a perfectly even effect should be treated with suspicion. | ||
