Authentication

The bracelet taper from lug width to clasp is specifically engineered; any aftermarket bracelet will have a visible step or gap at the clasp interface.

Known issues in the market
  • The integrated bracelet taper is smooth and factory-engineered; aftermarket bracelets cannot replicate the factory taper and will show a step or gap at the clasp.
  • The date at 3 must advance cleanly; any date advancement error on Cal. 1110P is a service indicator.

Common legitimate replacements
  • Integrated bracelets are the most commonly replaced component on pre-owned Polo Date examples; aftermarket options affect value and should be disclosed.
  • Cal. 1110P service intervals should be followed; an unserviced movement is a negotiating point on pre-owned examples.

Last reviewed June 2026

The Polo Date 42mm (G0A45001) uses caliber 1110P, an in-house automatic at 4.6mm movement height. This is a distinct reference from the Polo S (G0A41003), sharing the Polo family integrated-bracelet architecture but with a different caliber and slightly different case. The reference confusion between Polo S and Polo Date is the most common misrepresentation in this family.

Known reproduction risks

toggle
HIGH RISK

Undecorated movement bridges

  • Plain or brushed bridge faces without Cotes de Geneve
  • No anglage on bridge edges
  • Movement looks generically finished rather than Piaget-quality
MEDIUM

Reference confusion: Polo S vs Polo Date

  • "1160P" on caseback instead of "1110P"
  • Dial reads "POLO S" instead of "POLO"
  • Reference number on caseback does not match G0A45001

The Polo S and Polo Date are distinct references with different calibers and case designs. Grey-market misrepresentation of one as the other is the primary concern, rather than outright copying of either.

Dial variants by era

EraDescriptionIdentifiers
2019 to presentSilver, blue, or black dial with applied index markers and date at 3 o'clock. The Polo Date retains the integrated bracelet design with brushed and polished finishing. "PIAGET" at 12, "POLO" on the dial (not "POLO S"). The case shape is close to the Polo S but with subtle proportional differences.
  • Date window at 3 o'clock
  • "POLO" on dial (without "S" suffix) -- distinguishing from Polo S labeling
  • Integrated bracelet with brushed tops and polished flanks
  • 42mm case
  • Applied index markers
  • Silver, blue, or black dial options

Caliber distinction from Polo S

Original: Caliber 1110P is distinct from the 1160P in the Polo S. The 1110P is 4.6mm thick and uses an integrated bracelet movement architecture. The specific detail differentiating the two calibers is the bracelet integration design -- the 1110P was developed alongside the 2019 Polo case.

Replacement tells
  • "1160P" visible on caseback where "1110P" should appear (different caliber, belongs to Polo S)
  • Movement architecture visible through caseback inconsistent with 1110P layout
  • Decorated bridges absent -- both calibers require Cotes de Geneve
Bracelet

Original: Same dual-surface finishing as Polo S: brushed top faces, polished flanks, sharp transition. The Polo Date bracelet is functionally identical in finish quality to the Polo S.

Replacement tells
  • Uniformly brushed or polished links
  • Blurry surface transitions
  • Link proportions inconsistent with the Polo family bracelet geometry

Case back markings

toggle
2019 to present
  • Caliber 1110P designation
  • "PIAGET" with logo
  • Water resistance: 100m
  • Reference G0A45001 with serial number
  • "STAINLESS STEEL"
  • "SWISS MADE"

Movement tells

toggle
  • Caliber 1110P has a 50-hour power reserve. Power reserve depletion behavior is the same as the 1160P: a watch stopping before 24 hours from full wind has a movement problem.
  • Decorated bridges mandatory: Cotes de Geneve and anglage visible through the caseback display window. Same Piaget standard applies.
  • The 18k gold rotor is present (unlike the peripheral rotor on the 1160P in the Polo S). Verify the rotor is gold-toned with Piaget engraving.
