Cheapest Rolex Submariner 16803 Two-Tone Black Dial 1987

To set the time, unscrew the winding crown fully and pull it out to position two. Rotate the crown to adjust the hour and minute hands, avoiding the date change period between 9 PM and 3 AM.

To set the date, pull the crown to position one. Turn the crown clockwise until the correct date appears in the window. Never adjust the date when the watch indicates nighttime hours.

To wind the watch manually, ensure the crown is fully screwed in. Unscrew it and turn it clockwise approximately 30 times to provide initial power if the watch has stopped.

The unidirectional bezel rotates counterclockwise only. Align the triangle marker with the minute hand to track elapsed diving or timing intervals safely.

Secure the Fliplock clasp by pressing the safety latch until it clicks. The extension system allows adjustment over a wetsuit up to 5mm.

Rolex, founded in 1905, has built its reputation on the principles of precision, durability, and timeless design. Each Submariner, including this Ref 16803, undergoes rigorous testing to ensure performance in extreme conditions, embodying the brand's commitment to functional excellence. The transition to the 3035 caliber in this model marked a significant advancement in reliability and timekeeping accuracy.

The 'Clean Factory' reference in collector circles denotes watches preserved in outstanding original condition, like this example. This standard emphasizes minimal polishing, intact factory components, and honest patina, ensuring the watch retains its value and historical integrity. Our curation focuses on such specimens that tell an authentic story.

How often should I service this 1987 Rolex?

We recommend a complete service every 5-7 years for vintage Rolex watches. The Caliber 3035 benefits from regular lubrication, and gaskets should be replaced to maintain its 100-meter water resistance.

Can I swim with this two-tone Submariner?

Yes, after a pressure test confirming water resistance. The 16803 was originally rated for 300 meters, but for a 1987 watch, we recommend limiting to surface swimming unless recently serviced.

How do I care for the gold and steel bracelet?

Clean with warm water, mild soap, and a soft brush. Dry thoroughly. The two-tone construction requires gentle handling to prevent differential wear between metals.

Is the tritium lume still functional?

Tritium has a 12-year half-life, so the 1987 lume will not glow brightly but may show a faint emission in total darkness. The aged patina is valued by collectors.

What if I need replacement parts?

Genuine Rolex Service Centers can supply period-correct components. For this model, ensure they use tritium-matched hands and dial if replacements are necessary to preserve value.
