Dial and Display Configuration

The source describes the dial as a "Tropical dial in shades of brown with luminescent Arabic numerals, continuous seconds counter at 9 and 30 minutes at 3." Visual observation confirms the bicompax layout with a continuous running seconds counter at 9 o'clock and a 30-minute counter at 3 o'clock. The speckled brown dial is set with luminescent Arabic numeral hour markers and syringe-style hands, complemented by a central chronograph seconds hand.

Identity and Case Construction

Catalogued under the heading "DODANE" and model designation "Mod. “Type21 Flyback”, 1960s", this chronograph is listed with a "Diam. 38 mm" and a "Steel case with screw case back and rotating bezel." The listing text notes that this model was "designed in France by Dodane since 1950 and assembled in Switzerland". Direct visual inspection of the accompanying frontal image shows a round steel case fitted with pump pushers flanking a winding crown. It features a bidirectional rotating steel bezel marked with engraved hour numerals and a triangle at 12 o'clock, mounted on a brown leather strap with contrast stitching.

Reported Movement and Technical Background

The watch is listed with a "Hand-wound Valjoux 222 movement with very rare flyback function." The seller notes that it "was supplied to the pilots of the French “Air Force” fighter planes" and produced to "the technical specifications of the French Ministry of Defense with the fly-back chrono function; capable of compensating for the failure of the on-board devices used by the pilot as a navigation instrument." Because the available documentation is limited to an aggregator listing and a single frontal photograph, internal movement markings, caliber identification, and case-back inscriptions are not recorded in this source. Internal mechanical features and military delivery details remain attributed solely to the aggregator's description.
