A precious-metal expression of the Submariner Date, reference 16618 pairs the model's utilitarian foundation with the richer character of a 40mm yellow gold case and bracelet. The blue dial gives this watch the vivid, sunlit look collectors associate with the reference, balancing warmth and saturation without losing the Submariner's directness. An automatic movement and date keep the format practical. At 13mm thick, it wears with solid substance but remains classically proportioned.
