The IWC caliber 82650 is an in-house automatic perpetual calendar movement.

The 82650 is based on the IWC cal. 82000 framework with the addition of a perpetual calendar module on top.

This calibre was announced in the Portugieser Perpetual Calendar 42 in April 2020. It is also found in the Portofino Perpetual Calendar released in November 2022.

In IWC’s own words:

“In the Portugieser Perpetual Calendar 42, IWC has for the first time integrated the iconic complication in an in-house movement from the 82000-calibre family. The IWC-manufactured 82650 calibre’s Pellaton winding system, which is fitted with ceramic components, builds up a power reserve of 60 hours. The displays for the date, month, day of the week, moon phase and leap year are shown in three subdials at “3 o’clock”, “6 o’clock” and “9 o’clock”.”

Perpetual Calendar Functionality:

The IWC calibre 82650 is able to display the correct day, date, month and moonphase without being set by the user. It knows the different number of days in each month and advances accordingly. It also recognizes leap year and adds a leap day to February (29th) every 4 years – this is indicated with a small window at the bottom of the subdial at 9:00, counting the years until a leap year. When it is a leap year, the indicator will show a red L. The moonphase indicator is extremely precise and will provide an accurate display of the moon cycle for 577.5 years.

No soy un experto, pero creo que sé dónde he visto este calibre, en un Reef Tiger, aunque lo ponen como de fabricación propia, también tiene ese círculo dorado. Creo que es el mismo pero no puedo asegurar nada, solo que el reloj es bastante “caro” siempre hablando de marcas chinas. Me encanta su blog, soy un amante de los relojes y tengo una colección de mediana calidad, de más de 50 relojes. El último que compré tiene un calibre YN55A, que como he leído aquí es una copia de Orient, de ahí que ponga Edson. No lo tenía y… Read more »
