Stepping up in Jaeger-LeCoultre's range
The Reverso was designed in 1931 so that polo players could flip the case and protect the dial from a mallet strike. The Duetto takes that mechanism and gives both faces equal purpose: the front carries a silvered dial with vertical satin brushing and guilloché, printed with Arabic numerals and dauphine hands; rotate the case and a black dial framed by two rows of brilliant-cut diamonds faces outward instead. One movement drives both, and the choice of which to show is made at the wrist. At 21mm wide and 34.2mm from lug to lug, this sits closer to a bracelet than a watch in terms of physical presence, and at 38.5 grams it will barely register. The Calibre 844, built entirely in Le Sentier from 100 components, is thin enough to keep the case at 8.7mm — flat against the wrist and untroubled by a sleeve. Neither dial carries lume, which is consistent with what this watch is actually for: candlelight, not a dive torch.

Learn more about Jaeger-LeCoultre
Antoine LeCoultre opened a workshop in Le Sentier in 1833 and set about solving a problem nobody else had: precise measurement. His Millionomètre of 1844 was the first instrument capable of measuring to a micron, and it let the Vallée de Joux move from skilled approximation to genuine precision.
The house became the movement supplier to the industry. Patek Philippe, Vacheron Constantin, Cartier, and Audemars Piguet all built watches on LeCoultre ébauches, and the manufacture has produced well over a thousand distinct calibres — an output no other house approaches. The partnership with the Parisian retailer Edmond Jaeger, formalised in the company name in 1937, gave it the Jaeger-LeCoultre it still carries.
Two products define it in the public mind. The Reverso of 1931 was designed so British Army officers in India could flip the case and protect the crystal during polo; the reversible case became one of the few genuinely original watch designs of the century. The Atmos clock, developed from 1928, runs on atmospheric temperature variation and needs no winding at all.
The Duoplan and the calibre 101 — still the smallest mechanical movement in series production, introduced in 1929 — sit alongside the gyrotourbillons and minute repeaters that keep the manufacture at the technical front.
Richemont has owned the house since 2000.

Frequently asked questions, and things you should know about this watch
Can I swim with it?
No. At 30m it will survive rain and handwashing, but not submersion of any kind.
Will the glass scratch?
Unlikely. Sapphire is second only to diamond in hardness and shrugs off everyday marking.
Does it need a battery?
No. It is hand-wound, so it needs winding every day or two but never a battery.
How long does it run for when it's not worn?
About 38 hours fully wound — so it will usually stop if you leave it off overnight.
What size strap does it take?
15mm. Any strap of that width will fit, and on most modern watches quick-release bars make the swap a two-minute job with no tools.
Will it fit my wrist?
Lug-to-lug is 34.2mm, which suits wrists from roughly 15cm (6 inches) upward.
Lug-to-lug decides fit more than case diameter does.
Is it a men's or women's watch?
Listed as women's, though at 34.2mm it sits in the range that suits anyone.
