Often it’s details that turn an extraordinary watch into something exceptional. Details such as sophisticated technical features. Or appealing design elements, such as those just waiting to be discovered in the 1739 St I 4N. Namely, the stylishly arranged golden hands, the appliqués, meticulously attached by hand and the silver electroplated dial with sunburst decoration – an interplay that creates a highly exquisite and elegant feel.

This timelessly classic design, skilfully incorporating elements from previous styles and thus illustrating a sense of tradition, is reinforced by the slightly curved, high-quality sapphire crystal. Such details define and characterise the overall appearance of this magnificent watch, which has a diameter of 39 mm.
