Object description

Object Identity and Configuration

This timepiece is identified as a Movado Ermeto Calendarmeto, a variant of the Ermeto line produced between the 1920s and 1960s. The source provides an approximate production date of 1940. The unit is described by the source as the second-largest sub-model in the series, with physical dimensions of 76 mm wide and 36 mm tall when the sliding case is fully extended.

The exterior features a covering of dark brown crocodile leather, which the source identifies as the original material. The design incorporates a pop-out rear stand, intended by the design to allow it to function as a desk or nightstand clock.

Dial and Complications

The square metal dial is signed 'MOVADO' and marked 'SWITZERLAND' at the base. It features luminescent-style outlined Arabic numerals with arrow indices at the cardinal positions.

Calendar complications include apertures for the day and month, positioned above and below center, respectively, and a moonphase crescent on the right. A concentric track numbered 1 through 31 tracks the date, indicated by a red-tipped pointer hand.

“Luminescent-style outlined Arabic numerals with arrow indices at the cardinals.”
“Central display includes an aperture for the day above center, month below center, and a moonphase crescent at right.”
“Concentric date track numbered 1 through 31 indicated by a red-tipped pointer hand.”

Mechanical Operation

The Ermeto utilizes a sliding travel case to drive the winding mechanism. Two internal opposing rails engage the center-mounted crown during the opening and closing movement. The source claims that six cycles are sufficient to provide 24 hours of operation, in addition to standard manual crown winding.

The movement caliber remains unrecorded in the source. The source reports that timekeeping, calendar advancements (day, date, and month), and moonphase functions are currently operational.

Evidence for this section

“There are two opposing rails, that when the case is opened and closed, spin the center mounted crown.”
“It is reported that it takes just SIX opening and closings of the case to wind the watch enough for 24 hours of operation.”
“All functions work…timekeeping, day advance, date advance, month advance, and moonphase advance”

Open research questions

What is the specific movement caliber used in the Movado Ermeto Calendarmeto?
Are there internal case hallmarks present to verify the circa 1940 production date?
