'''Sigma dial.''' Dial with σσ symbols flanking SWISS at the 6 o'clock chapter, denoting gold-applied hour markers. Swiss-industry convention for identifying precious-metal components. Appears ~1972–1978 across both [[Reference:6263|6263]] and [[Reference:6265|6265]].

'''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]].

'''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. Benjamin Clymer's 2013 Hodinkee piece treats it as a factory Rolex variant; Jose Pereztroika at Perezcope (2025) reads it as a 1990s Tom Bolt construction. See [[Reference:6263|6263]].

'''Tropical.''' Production-period black dial that oxidised to brown under UV exposure or heat. Aged production dials valued for patina rather than a separate factory variant. Distinct from Patrizzi, which affects only the sub-dial outer rings.
