The tonneau-shaped case measures 40mm across and just 8.95mm thick, with a lug-to-lug span of 41.5mm. Its construction pairs a brushed titanium case middle with polished stainless steel for the bezel, lugs, and crown — a combination that keeps weight down while varying the surface finish across the watch. The forest green dial is lacquered and carries a horizontal stamped texture. Rhodium-plated, diamond-cut indices and matching hands catch the light cleanly, with blue-emission Super-LumiNova applied to both. The minutes track spells out "LOUIS ERARD" in place of numerals, and an oblong applique at three o'clock carries the brand's initials. The domed sapphire crystal has anti-reflective treatment on both sides. The integrated bracelet uses satin-finished titanium outer links alongside polished stainless steel centre links, tapering from 28mm at the case to 20mm at the concealed butterfly clasp. Inside runs the Sellita SW300-1, an automatic calibre at 4Hz with a 56-hour power reserve.

Learn more about Louis Erard
Louis Erard was born in La Chaux-de-Fonds in 1893, into a town then producing a large share of the world's watches. He worked in its workshops, founded a watchmaking school in 1929, and set up a casing and assembly business with André Perret the same year. The first watches under his own name followed in 1931.
Assembly was the trade at the time: components came from independent artisans and the assembler built, adjusted and finished the watch. By 1937 Erard employed more than sixty people and was selling internationally.
The quartz crisis did its usual damage. The company was sold in 1991 and production moved to Le Noirmont in the Jura, then sold again in 2003 to a group led by Alain Spinedi, who refocused it on mechanical watches at prices that undercut everyone doing similar work.
The regulator became the signature — the dial layout that separates hours, minutes and seconds onto their own axes, borrowed from precision reference clocks, and rarely seen at this price.
What has made the brand's recent reputation is collaboration: limited editions with independent watchmakers whose own work is unobtainable, among them Vianney Halter, Konstantin Chaykin and Alain Silberstein, on Sellita and Valjoux movements.

Frequently asked questions, and things you should know about this watch
Can I swim with it?
Showering yes, swimming no. 50m covers splashes and brief immersion, but a swimming stroke generates well above the pressure that figure describes.
Water resistance explainedWill the glass scratch?
Unlikely. Sapphire is second only to diamond in hardness and shrugs off everyday marking.
Sapphire, mineral and acrylic comparedDoes it need a battery?
No. It is automatic — the motion of your wrist winds it, and there is no cell to replace.
Quartz, automatic and solar comparedHow long does it run for when it's not worn?
About 56 hours fully wound — enough to survive a night off the wrist, but not a full weekend.
Is it a men's or women's watch?
Listed as men's, though at 40mm it sits in the range that suits anyone.
