About the Duomètre family
The Duomètre was introduced in 2007 around the Dual-Wing concept: two separate energy systems in one movement, one for the timekeeping and one for the complication, so using the complication does not affect accuracy. Many models also show the time to a sixth of a second.
In 2024 Jaeger-LeCoultre renewed the line with models such as the Duomètre Chronograph Moon, and the catalog's references use calibers listed as 381 and 391. The catalog lists stainless steel, pink gold and platinum references. Dealers identify the function and metal and ask for service history, since the movements are complex.
