Put all the parts in the watch cleaning machine for 6 minutes per bath. Some parts are ridiculously expensive if you can find them.Other parts are just obsolete and you can’t find them anywhere.
On display is the Longines L897 calibre with 21 jewels, which is based on the ETA A31. It has a comfortable 64-hour power reserve, beats at a less common 25,200vph (3.5Hz), and has hours, minutes, central seconds and a month-date annual calendar complication.
Invented by Patek Philippe in 1996 (with the reference 5035), this sophisticated complication often comes at a significant cost, but at just below 2K Euros, the Longines Master Collection Annual Calendar is the most affordable entry into an annual calendar piece.
You can see examples of much more expensive annual calendar watches at our Annual Calendar Buying Guide.
The Master Collection Annual Calendar comes in a series of four models.
Two models have silver dials with stamped barleycorn finishes, one with large Arabic numerals and the other with diamond hour indices.Hands are either rhodium plated or blued steel, depending on the model. Thus consider this watch more of a dress/business timepiece.
