· Quarter-repeater by two hammers on two steel gongs (activated by depressing the pendant); safety bolt locking the repeater’s functions (slide located on the case-band at 1 o’clock)
Case-back guilloché (engine-turned), with, in the centre, a circle; guilloché (engine-turned) case-band; gilded metal cuvette (dome)
White enamel dial, with suspended “Breguet” numerals; blued steel “Breguet” hands.
Movement, 21’’’, gilded brass, going barrel, cylinder escapement, monometallic balance (silvered brass) and blued steel flat hairspring, blued steel index-regulator with temperature compensating bimetallic curb and pare-chute; repeater work on the main plate, under the dial; additional and added keyless-winding mechanism, a kind of folding key made of blued steel directly positioned on the barrel shaft with a ratchet to be able to be properly repositioned in the cuvette (dome) which has been drilled for this purpose, the Maltese cross stop being preserved, with a folding time setting key acting directly on the centre wheel made in the same way (transformations probably dating from the middle of the 19th century).
