Ebel 1911 BTR Automatic Perpetual Calendar Chronograph

1911 BTR Automatic Perpetual Calendar Chronograph is a wristwatch by Ebel.

Luxury model from the men's collection Ebel 1911 BTR: a chronograph with the complication of a perpetual calendar, which is highly esteemed by connoisseurs.

The high-precision astronomical moon phase works far more accurately than conventional moon phase indicators: A deviation of one day arises only after 122 years, while it occurs at a standard moon phase after just over 2 1/2 years. The functions of the perpetual calendar are set using four correctors at the sides of the housing. They can be operated with a special pen.

The watch is available in three limited editions: stainless steel, 18ct rose gold or 18ct white gold.
