Authentication guide

Last reviewed June 2026

The Pontos Day Date runs the in-house ML156 caliber with a day-date display; the round 41mm case, applied indices, and ML manufacture movement are the authentication anchors.

Known reproduction risks

toggle
LOW

The Pontos is a mid-tier dress watch; not a frequent reproduction target.

  • Applied marker edges should be sharp under 10x magnification.
  • ML manufacture movement visible through caseback is the fastest verification.

Dial variants by era

Service part flags

toggle
Day disc

Original: Day disc cycling through abbreviated day names; should advance at midnight.

Replacement tells
  • Day disc that shows only date without day names is a different caliber variant.
  • Day disc with incorrect language set for the listed market (regional variants exist).
Hands

Original: Leaf or dauphine hands with polished flanks and luminous fill.

Replacement tells
  • Baton or sword hands in place of the leaf style indicate non-original parts.

Case back markings

toggle
2004 to present
  • MAURICE LACROIX PONTOS
  • ML156 caliber designation
  • SWISS MADE
  • Display caseback on most variants

Movement tells

toggle
  • The ML156 is the in-house day-date caliber; the ML-signed rotor and manufacture finishing should be visible.
  • Day mechanism is integrated into the movement base, not a module; if the caseback shows a modular day mechanism mounted on top of a standard ETA, the caliber has been substituted.
