The French Era….

From the 1930s through the postwar years, Lowenthal watches were sold throughout the French-speaking world, including by prestigious retailers such as Hermès, where many examples were signed with the maison's name. At a time when most men's wristwatches remained modest in size, Lowenthal produced oversized models reaching up to 41 mm in diameter, offering a distinctly modern presence on the wrist.

It was a golden age of motoring and mechanical craftsmanship. Chronographs accompanied gentlemen drivers on the roads between Paris, Monaco, and the Riviera, serving as practical instruments for precise timekeeping.

The surviving Lowenthal timepieces from this period reflect the values that continue to define the maison today: mechanical purity, restrained luxury, and enduring craftsmanship.
