Hello! This is Kaneko from Commit Ginza, and I would like to introduce a recommended timepiece! Today, we have a rare, solid gold Datejust featuring a natural stone dial.

Rolex Datejust Onyx
Ref.16018 Serial. R5 (manufactured around 1987-88)
Cal.3035 8385MEX
Accessories: International Service Warranty (June 2026)
Store Sales Price 12,430,000 JPY (tax included)

The solid gold Datejust model "Ref. 16018" has just arrived!

This is an early 5-digit reference Datejust, produced from around 1977 to 1988. It features a classic 36mm case diameter, with an 18K yellow gold case and a fluted bezel, making it a luxurious solid gold model.

Compared to the previous Ref. 1601 series, the movement has been upgraded to the Cal. 3035, which offers a higher beat rate and a quick-set date function.

Furthermore, the adoption of a sapphire crystal significantly improves its practicality. The combination of the presence that only solid gold can offer and the quintessential vintage aesthetic makes this a truly attractive model.

The piece we are introducing today features the rare and beautiful "Onyx dial," known for its deep, jet-black luster!!

Onyx is a natural stone known for its deep, jet-black hue and beautiful gloss.

While it is a rare stone dial along with materials like Lapis Lazuli, the popularity of Onyx in recent years has been phenomenal—it wouldn't be an exaggeration to say it is currently the most dynamic stone dial out there!!

This is a fast-moving model that tends to sell out quickly every time it arrives at our shop.

While Onyx dials with diamond indices do exist, the most popular choice is undoubtedly the clean, non-index dial we are showcasing today!!

The contrast of the gold crown, hands, and lettering against the jet-black dial creates a unique, incredibly stylish atmosphere!!

It pairs perfectly with the solid yellow gold, giving it a presence that is completely different from a standard Datejust!!

Unlike stones like Lapis Lazuli where you enjoy the natural patterns and textures, the charm of Onyx lies in its flawless, uniform jet-black beauty.

The marking at the 6 o'clock position reads only "SWISS," identifying it as what is known as an "Only Swiss" dial. Differences in these markings can be found depending on the era, and these fine details are one of the interesting points of this piece.

The condition of the dial is excellent, and it remains clean with no cracks or damage to be found!!

This piece is highly recommended as the case and bracelet are also in great condition!!

Look at the condition of the middle case!! It retains its original form, which is quite appealing.

The lugs are thick and the edges are sharp! The hairline finish is also in beautiful shape!!

The President bracelet equipped on this watch is also quite rare!!

The clasp bears the "MEX" engraving, making this what is commonly known as the "Mexico bracelet." It is a rare specification that differs from standard President bracelets and is extremely difficult to find in the market.

The bracelet is in good condition with only very minor slack!

Accessories include the International Service Warranty (dated June 2026) and repair details.

The fact that it has recently undergone a manufacturer overhaul is a major plus!!

Wrist shot!!
On the wrist, the jet-black of the Onyx stands out even more!!
It’s simple yet incredibly cool!! This sense of presence is just irresistible!!

Rolex Datejust Onyx "Ref.16018 Serial R5"
This is a piece featuring a rare Onyx dial that has been growing increasingly popular in recent years!
The fact that it comes with the even rarer Mexico President bracelet is something you shouldn't overlook!!
Stone dials are becoming rarer every year, and it’s a model that is hard to expect to see in the future!
With its overall excellent condition, I highly recommend this watch!!
To all our stone dial collectors, please be sure to consider this piece.
