Buying an expensive watch online is scary considering the extensive network of scammers out there. I took every precaution I could before I purchased a Rolex from Igor at Diamond Source NYC. All said and done, Igor did everything he promised. He is honest, responsive and very respectful. Upon receipt of the watch it was exactly as described. Beautiful, unworn and 100% authentic. This guy can find anything you’re looking for. Thanks Igor.

Took a good amount of time to assess what I had and gave me top dollar matching and exceeding another estimate. They even allowed me to watch them count the cash given to me. I would come back to work with them again.

My overall experience in my first ever purchase of a luxury watch from Diamond Source NYC is nothing but a thrilling and exemplary experience. From inquiry to shipping, Igor has been outstanding in helping me from video inspection of the watch to next day shipping to my address. Most of all, I received a lovely watch, excellent like-new condition , excellent packing, and the watch itself is truly authentic complete with box and papers.

Igor is a good guy and has good business. If you want a watch this is the place to go to.. talked with multiple people to source a watch I wanted and he took care of me and was able to be competitive to everyone else’s prices. He is in it for the long term relationship opposed to trying to make the most off of someone initially. He’s earned a long term customer for life and will be getting every future watch from him. Look forward to growing the collection and having someone I know will not take advantage and will get me the best piece for the best price!

The Vintage Icon: Rolex Day-Date 36 Reference 1803 Watches for Sale in NYC
Pre-Owned & New | NYC Diamond District

Questions? Call (212) 730-5959 or visit us at 20 W 47th St, Suite 401, New York, NY

The Rolex Day-Date Reference 1803 is one of the most recognizable and enduring vintage references in the entire Presidential line.

Produced primarily from the mid-1960s through the late 1970s, this timepiece is defined by its classic 36mm proportions, the warm vintage aesthetic of its Acrylic Crystal, and its powerful, historical significance. Available in Yellow Gold, White Gold, and Everose Gold, the 1803 is the quintessential Day-Date for the true collector. Welcome to Diamond Source NYC, your authoritative source for authentic, authenticated Rolex Day-Date 1803 Vintage Watches.

We offer competitively priced, expertly inspected preowned models for sale right here in NYC, guaranteed complete with transparent provenance documentation.


The Defining Characteristics of Reference 1803

The 1803 retains the legendary 36mm Oyster case, perfectly balanced and comfortable for daily wear. Its most cherished vintage attribute is the beautiful Acrylic Crystal (plexiglass), which offers a unique dome profile and soft distortion that appeals strongly to collectors. This reference is most commonly found with the iconic Fluted Bezel and is paired with the classic, semi-circular three-piece link President bracelet. The dial variation is vast, ranging from simple sticks and applied markers to exotic variations like bark, tapestry, and lacquer finishes, including the desirable 'Stella' dials.

The Heart of Vintage: Calibre 1555 and 1556 Movement

The Day-Date 1803 utilized the venerable Rolex Calibre 1555 (early models) or the Calibre 1556 (later models), both of which featured the "Non-Quickset" function, meaning the day and date are advanced by winding the hands 24 hours. While not as convenient as modern movements, this feature is highly characteristic of the era. These robust, self-winding mechanical movements were pioneers in achieving the Day-Date's precise calendar function and cemented Rolex's reputation for enduring reliability.

Investment and Collectibility: Enduring Vintage Value in the NYC Market

The Rolex Day-Date 1803 price remains robust, reflecting its deep history, vintage charm, and high demand among watch enthusiasts and collectors. The condition of the case, the quality of the dial patina, and the tightness of the original President bracelet are key factors determining its valuation. Diamond Source NYC specializes in the provenance and authentication of these vintage pieces, ensuring every timepiece is inspected and documented thoroughly. Secure this definitive icon of vintage luxury and history today from our curated inventory.
