Rare sports model made for the middle East market (with the Middle East Eagle icon on the dial). This watch is unique as Rolex no longer allows co-branding in its watch dial.
The daytona model has been popularised by Paul newmen in the movie. The early daytona uses non-Rolex movement and they are manual movements (Valjour).
Rolex don't make any more moonphase watches. Since the late 1950s
These were the early so called "complicated" movement with day, date, time, moonphase, chronograph functions all into one at that time!
The 6062 Moonphase watch and the questionable 81806..
The Rolex Prince is One of THE classic!
Dusring the 1930s, the price of the Rolex Prince is equvalent to the price of a car!
It is widely known as a doctor's watch as it has a large separate subsidiary second dial for ease of reading for doctors when measuring the pulse rates of the patients.
Rolex has recently re-launed a new Prince series but the feel of the watch is different (Please see enclosed photo).
Like the bubblebacks, the Rolex Prince comes in many variations, steel, gold (9k, 14k, 18k), silver, gold and steel, tiger straps etc.
The Gruen doctor's watch and the Rolex Prince shared the same movements as the former were made for the US market while the latter were made for the rest of the world. They were not sold as competitors. However, the price of the Gruen is 30% of that of a Rolex. That's the power of brand building!
Rolex Prince - Watch History
The Rolex Prince has its place in watch making history as being one of the most groundbreaking watches released. Rolex released this watch in 1928 and its accuracy and ease of use set the standard for luxury watches. The Rolex Prince featured a stylish rectangular shape as well as two easily legible dials. Hours and minutes were tracked by the larger dial on top and seconds were counted on the smaller dial on bottom.
On initial release, the prince was available in two case styles, one was a more rectangular case (Classic) and the other was a much rounder design (Brancard), the choice of materials was yellow gold, sterling silver, platinum, and two tone combinations (steel was available later on). Brancard model watches were designated model 971 and Classic watches were model 1343. Shortly after its release, the Rolex Prince was augmented with a self winding movement, which eliminated the need for winding.
The “Railway Prince” was released in 1935 and was designed after the look of locomotives, this model was designated 1527. Rolex then introduced a new movement which was nicknamed “Jumping Hours”. This design would only feature minute markings on the larger top dial, with a slot open at the top (12 o’clock position) with a number display (1-12 Hours). As the minute hand swung past the hour display, the number would switch over to the next hour. This would also serve as the inspiration for the Rolex Datejust down the line.
One of the last models of the Rolex Prince was the “Super Precision Aerodynamic” version. It featured a singular large dial where the hour, minutes, and second hands all lived. The Rolex Prince line would be discontinued sometime in the 1940’s and replaced with the more circular and sporty designs.
Special Edition Rolex Prince Watches
Throughout its production period, the Rolex Prince watch has had numerous production runs as special editions. The “Sporting Prince” was a pocket watch that was designed to be used while engaged in athletic activities. It was contained in a case that would activate a spring mechanism that would present the dial to the user by popping out and tilting.
A large Canadian department store commissioned Rolex to create special edition versions of the Prince to give employees that have worked for more than 25 years, appropriately named the “Quarter Century Club”. These watches had the words “1/4 Century Club” printed on the edges of the hour and minutes dial instead of number markings.
I love the Rolex bubblebacks! One of my key collections are the vintage Rolex Bubbleback as these are the first fully finctional automatic watches produced in the 1930s. What attracts me was its unique protruding backcase (which is why it was called bubbleback).
There are many versions namely: in steel, half gold, gold (9k, 14k, 18k Pink or Yellow gold) and hooded version as well as the varies sizes and dials.
One of the rare ones that I have is the one with the hooded bubbleback in pink gold (made for the USA market) as well as the one with 9 Rolex crowns, and the California dial!
Some additional information from the net. The bubbleback was Launched in 1933, it was also one of the early Rolex models. The creation of this model was a significant event for Rolex because it featured the first Auto-Rotor. Rolex is not the first to create the automatic movement. Harwood was one of the pionner. However, The Auto-Rotor signified Rolex's success in developing a self-winding movement and what differntiates it from the competitors was its reliability. Today, the Bubbleback is one of the most sought after and collectible wristwatches in the world because production was discontinued in the early 1960s.
How Did Rolex Succeed in Creating the Bubbleback?
In the 1920s, numerous watch-making companies were trying to create a self-winding movement. They kept attempting to incorporate slight modifications to Harwood's self-winding watch that featured a no winding stem. However, Rolex was following altogether a different path. It experimented with its existing movements and looked for a new solution to the old challenge. Finally, in 1931, Rolex created the Auto-Rotor movement from an existing Aegler movement (subsidiary seconds Hunter 8-3/4"). This invention resulted in a "perpetual motion" wherein the winding mass could turn smoothly both clockwise and counter-clockwise and pivot a full 360 degrees on its staff in the center of the movement. In 1932, Rolex patented its first successful self-winding perpetual wristwatch. One year later, the Rolex Bubbleback was introduced into the market. Due to unsuccessful attempts in the past and the resulting skepticism in the public eye, Rolex tried to publicize this new model as "the watch sensation of 1934".
How the name Bubbleback come about?
The fascinating historical marker is the watch never had "Bubbleback" engraved anywhere on it, and was never officially designated that title as it was a term coined by the watch collectors. Instead, it bore "Rolex Oyster Perpetual" just below the 12 o'clock position. How did it come to be known as "Bubbleback?" The answer lies in its bubble-shaped, thicker case back. The thick Auto-Rotor led to an over-sized mechanism which needed a thicker case. Another nickname for this model had been "Ovettone," an Italian word meaning "little egg." for the Hong Konger, it was known as the "Little coffin" 倌材仔.
Notable Changes Introduced Over Time
The first Rolex Bubbleback was the model 1858 powered by the Ref.520 movement. The sweep versions were powered by the Ref.530 movement. The earliest Bubbleback models featured a 3-piece case and a deeper case back. In 1936, Rolex rolled out two new models: 3131 and 3132. Both these models sported a new 2-piece case and new modified movement 9-3/4". The only difference between the models was that while the Model 3131 was powered by the Ref.620 (subsidiary seconds), model 3132 was powered by the Ref.630 (sweep seconds). It is interesting to note that the early Bubbleback watches were the first Rolex models to be made available in the stainless steel material known as Steelium. Some models were also made available in Rolesor (steel and gold combination). The two terms, Steelium and Rolesor, were coined by Rolex and subsequently patented in 1931 and 1933, respectively.
A significant breakthrough took place in 1935 when the Bubbleback models were equipped with a new streamlined balance wheel known as the "Super Balance." This improved the functioning of the Auto-Rotor. Rolex went one step further by marketing its Bubbleback models in three sizes so that they could appeal to men and women alike. In 1941, a ladies Bubbleback model was launched, powered by the Ref.420 movement. However, no sweep version of the model was made available for ladies. Later, in the 1950s, some Bubbleback models--such as model 5018--were introduced featuring "Bombe lugs".
Many other modifications, cosmetically as well as technically, were introduced over time, finally leading to the development of a new Rolex model called the"Big Bubbleback”. The Big Bubbleback led directly to the development of the Rolex Datejust, which eventually became one of the flagship Rolex models.
I love watches! Especially vintage watches!
I have been collecting vintage watches since 1988~~
I started collecting watches when I was still in the university. I would source for T shirts from the factory and then sell them in University to earn money for the building of my vintage watch collection.
the 1980s-90s were the peak of the vintage watch collection. After 1997 the financial crisis, the fever for vintage watch collection seemed to cool down. Following which, many began to collect the newly produced watch instead of the vintage one owing to easy availability and ease of purchase.
Nevertheless, vintage watches remain my true love!
