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!

Rolex Datejust 31 Reference 178243 Pre-Owned & New | NYC Diamond District

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

Diamond Source NYC continues to lead the New York luxury watch market by providing an unmatched selection of the Rolex Datejust 31 series. The Reference 178243 represents the quintessential Rolex aesthetic, blending traditional yellow gold with modern steel.

Our experts in the Diamond District carefully vet each 178243 to ensure it meets our rigorous standards for authenticity and performance, offering our clients a secure and premium purchasing experience for this iconic mid-size model.


The Timeless Appeal of Yellow Rolesor

The Reference 178243 is defined by its Yellow Rolesor construction—the legendary combination of 904L Oystersteel and 18k yellow gold. This marriage of metals has been a Rolex signature since the early 1930s. In this model, the strength and reliability of the steel case are complemented by the prestige and luster of the gold bezel and center bracelet links, creating a balanced look that has remained fashionable for decades.

The Modern Domed Bezel Design

Setting the 178243 apart from more ornate versions is its smooth, domed bezel. Crafted from solid 18k yellow gold and polished to a mirror finish, the domed bezel offers a sleek, streamlined profile. This design element provides a more minimalist and modern approach to the two-tone Datejust, making it an ideal choice for those who appreciate the luxury of yellow gold without the traditional aesthetic of a fluted bezel.

Calibre 2235: A Legend in Accuracy

Reliability is a hallmark of the 178243, powered by the Perpetual Calibre 2235. This self-winding mechanical movement is a certified Swiss chronometer, a designation reserved for high-precision watches that have passed the COSC tests. Equipped with a hairspring that offers great resistance to shocks and temperature variations, the Calibre 2235 ensures that the Datejust 31 remains a dependable companion for daily wear.

The Perfect Mid-Size Proportion

At 31mm, the Reference 178243 occupies the perfect middle ground between the traditional "Lady-Datejust" and the larger "Datejust 36." This size has gained immense popularity for its contemporary presence on the wrist while maintaining an elegant silhouette. Whether configured with the sporty Oyster bracelet or the intricate five-link Jubilee bracelet, the 178243 provides a comfortable fit and a high level of versatility for any occasion.
