Dauphine Hands

Against the brushed silver dial, dauphine hands and an outer minute track lend crisp definition to a balanced composition anchored by small seconds at 6 o’clock. Diamond hour markers at 12, 3 and 9 o’clock punctuate the applied baton indexes, giving the restrained dial its distinctive jewellery-watch character. The single small-seconds register forms a second visual zone within its rectangular border, with concentric grooves and a fine needle hand adding delicate detail.

14K GOLD

The rectangular 14K white gold case balances a curved profile with stepped lugs, while its narrow polished white gold bezel keeps attention on the dial. Side and end views reveal the longitudinal curve, stepped lug shoulders and contrast between polished surfaces and brushed lug ends. Fixed bars between the lugs secure the open-ended strap, while a slim coin-edge crown provides a finely ridged detail at the case side.

At its heart is the 17-jewel, hand-wound Gruen Cal. 420, a Precision caliber that the specialist Gruen Movement Catalog lists as introduced in 1942. The exposed mechanism reveals its balance and winding train alongside Gruen signing, the 420 caliber marking and the explicit “SEVENTEEN 17 JEWELS” inscription.
