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!

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

Acquiring a timepiece as brilliant as the Rolex Datejust 278384 requires a partner who understands the nuances of high-jewelry horology.

At Diamond Source NYC, we pride ourselves on being the city’s most trusted destination for those seeking the radiant, mid-size elegance of this 31mm masterpiece. Whether you are searching for a brand-new, factory-fresh model or a meticulously inspected pre-owned selection, we specialize in delivering an unparalleled experience tailored to your specific taste.

We recognize that our customers value the intersection of prestige and craftsmanship; our team works diligently to procure the exact dial and bracelet configurations you desire, ensuring your next Datejust is a perfect reflection of your personal style.


The Datejust 31 278384: A Harmonious Blend of Size and Brilliance

The Reference 278384 stands as a definitive choice for those who find the classic 28mm too delicate and the 36mm too bold. This 31mm mid-size model is defined by its stunning diamond-set bezel, where Rolex’s master gem-setters have meticulously placed high-quality stones into the 18ct white gold surface. This feature elevates the Datejust from a luxury tool watch to a piece of fine jewelry, offering a dazzling presence that remains sophisticated enough for daily wear while providing an unmistakable air of luxury.

The Luster of White Rolesor and Gem-Set Craftsmanship

The 278384 features the iconic White Rolesor construction—the signature Rolex marriage of durable Oystersteel and lustrous 18ct white gold. On this specific reference, the white gold is utilized for the bezel to provide the perfect, reflective backdrop for the diamonds, while the rest of the case and bracelet are forged from high-performance Oystersteel. Whether you are adding a new model to your collection or selecting a pristine pre-owned piece, the 278384 offers a bright, monochromatic aesthetic that serves as a versatile anchor for any jewelry ensemble.

Precision Engineering with the Calibre 2236

Behind the brilliant exterior of the 278384 lies a powerhouse of technical innovation. This model is equipped with the Calibre 2236, a self-winding mechanical movement that features the patented Syloxi hairspring in silicon. This technology provides exceptional resistance to magnetic fields and temperature fluctuations, ensuring the watch maintains its "Superlative Chronometer" status in any environment. At Diamond Source NYC, we emphasize that while the 278384 is a jewel of a watch, it is also a high-precision instrument built to the most exacting standards of Swiss watchmaking.

Expert Sourcing for Rare and Elegant Dial Variations

The versatility of the 278384 is further highlighted by its diverse dial options, ranging from the classic mint green and dark grey to the opulent mother-of-pearl and diamond-paved variants. Navigating these choices is a highly personal experience, and Diamond Source NYC is here to provide the insights and procurement expertise necessary to find the exact configuration that speaks to you. Our commitment is to manage the acquisition of your 278384 with the professionalism and discretion that defines the New York luxury market, ensuring your experience is as rewarding as the timepiece itself.
