This particular model hails from the celebrated Submariner line, renowned for its blend of rugged functionality and refined aesthetics. The reference 16610 is a classic in its own right, known for its robust stainless steel construction, precision automatic movement, and water resistance up to 300 meters.

What sets this piece apart, however, is its ‘Swiss Only’ dial. This unique feature dates back to a brief period in the late 1990s when Rolex transitioned from tritium to Luminova for its luminescent material. This watch is a Swiss Only dial, these dials were produced in a limited run between 1998/1999. Prior to 1998 dials used tritium lume and were signed ‘Swiss – t <25’, in 1998 Rolex introduced Luminova and changed the dial to ‘Swiss’ only. Shortly after Rolex switched to Super Luminova and adjusted the dial to ‘Swiss Made’. The serial begins with Axxxxxx dating this watch correctly to 1999.

Watches produced during this time bear the ‘Swiss Only’ mark on their dials, making them highly sought-after by collectors worldwide.

The watch features a 40mm case, offering a substantial yet comfortable presence on the wrist. Its unidirectional rotatable bezel with a scratch-resistant black insert allows for safe timing of dive sessions or other events.

The dial, in classic black, offers excellent contrast with its white hour markers and Mercedes hands, both filled with luminescent material for optimal legibility under all lighting conditions. Additionally, the date window at 3 o’clock, magnified by Rolex’s signature Cyclops lens, ensures easy reading of the date. 

With its combination of enduring style, robust performance, and unique historical significance, the Rolex Submariner with ‘Swiss Only’ dial is more than just a timepiece; it’s a conversation piece, a testament to Rolex’s horological heritage.
