The 1887 Remontage Manuel (where the number 1887 stands for the year of the Maison's foundation) is driven by the manufactory-made EB140 calibre (14'' diameter, 28,800 vibrations per hour, 18 jewels, power reserve of more than 40 hours), a hand-wound mechanical movement featuring an architecture specially created in the Maison's workshops in La Chaux-de-Fonds. The movement is characterised by meticulous attention to detail, particularly with regard to the balance bridge and the large gear-train bridge, both rhodium-plated, with vagues circulaires machining in the centre and colimaçon papier perimeter. The screws are blued and the engravings gilded. The 1887 Remontage Manuel employs a 41.80 mm steel case surrounding a blue guilloché-engraved dial with a clous de Paris motif with vintage charm. The same dial houses facetted Dauphine hands, rhodium-plated Roman and geometric numeral hour markers, and a date window with a trapezoidal aperture at 6 o'clock. The House logo at 12 o'clock is part of the historical heritage of the Maison and is documented in the archives from the early 1900s. The caseback is fitted with a sapphire crystal window to allow the EB140 calibre to be fully appreciated. The watch is combined with a blue alligator strap with a steel buckle.
