Rolex Prince Jumphour Chronometer Sterling Silver c1930

Rolex

The late 1920s and early ’30s saw Rolex at its most creative and dynamic. Having launched the world’s first truly waterproof and commercially successful (Oyster) watch in 1926, this relatively young company, est. 1906, went on to launch its first automatic waterproof wristwatch, the Oyster Perpetual Chronometer in 1934. These groundbreaking achievements are the foundations on which the company we know today was built. However, even at this early stage of development, this highly ambitious company offered a wide range of models to the market, many of which we seldom see today, due to relatively low production numbers.

Description

The Rolex Prince with the two dials is often referred to as a ‘doctors watch’ or ‘duo-dial’. The large seconds dial enabling the wearer to time heart beats, etc more accurately.  The Rolex Prince was first produced in 1929 and it has a special movement, initially made by Aegler and Wilsdorf , when in 1927 a patent was filed for a “shaped watch movement with a seconds dial”. In this new watch the winding barrel and the balance wheel were at opposite ends of the movement allowing for a larger balance wheel and thus more accuracy. A larger winding barrel also meant that the watch could run for longer on a single wind.

Here we have the incredibly rare sterling silver vintage Rolex Prince Jump-Hour Chronometer version of this watch in beautiful fully original, unrestored and untouched condition.

The Dial

As mentioned above this rare Rolex Prince dial was made with a purpose. This particular example has an original, unrestored and untouched off-white dial with standard Arabic numerals, a minute railtrack completes the top dial and is complete with a rare roulette jump hour aperture at ’12’ and the dial carries a perfectly proportioned subsidiary seconds dial at the bottom. Both the dials on this watch are swept by blued steel hands. All of these many aspects piece this wonderful watch together perfectly.

This watch is signed ‘Rolex and ‘Chronometer’ in the centre of the top dial.

This dial is original, unrestored and untouched. It is also in really excellent condition considering the age of the watch, with even fading, little spotting or crazing and with an even overall patina. Due to its relatively good condition and for reasons of retaining the character and the originality of the watch, we have left it completely alone. If however, you would prefer the dial sympathetically restoring, we will be happy to arrange this for you without any extra charge.

Please note, studio lights, professional-grade digital cameras, and macro lenses can be very unkind to an unrestored vintage watch dial. Also the dial here measures less than 1.25 inches across, so the image you’re seeing may be between 5 – 25 times larger than the watch itself. Therefore please keep in mind you are seeing many tiny flaws which cannot be seen, or will be very hard to see with the naked eye, even under close examination. Suffice to say, on the wrist, in natural light, this dial looks much better and carries a great deal more charm than the photographs portray.

The Movement

The movement fitted to this watch is a very high quality, 15 Jewel hand-wound movement used in Rolex’s highest quality watches of this period. The movement is in very clean condition having just completed a full overhaul and service by our vintage Rolex specialist watchmaker. This means it has been completely dismantled to each of its component parts before cleaning and inspection under high magnification, replacement where necessary with only genuine Rolex parts, then careful reassembly, adjustments and oiling to Rolex specification, before final calibration and testing.

The movement is therefore now running accurately and within expectations of 30 seconds per day. The timing expected of a Rolex movement of this period is within 1 minute per day, and this is our guarantee. The power reserve when fully wound on this movement is 30 hours. We are therefore confident in offering this watch with a 12-month written warranty*. Please note, Rolex watches of this period are reliable and accurate by the standards of their day, however they do need to be treated with extra care.

The movement is signed ‘Rolex Hairspring’, ‘Extra Prima’ and ‘Swiss Made’, this movement also carries the Rolex serial number 75576.

*Please note – our 12 months’ warranty is only applicable if the full list price is paid.

The Watch Case

The sterling silver case is very impressive with its slightly curved lugs and it is in spectacular condition. It measures 23mm across, excluding the correct Rolex unsigned crown, and 35mm from top to bottom. This may seem a little small, but it is, in fact, quite a large watch for the period, especially when one considers it is 47mm across the diagonal, including the lugs. The two-piece case is not hinged, but is opened using the bottom lip and swings open, revealing the dial. The movement can then be removed without any tools by holding the upper case and gently lifting the case back away from the main case – not recommended for the inexperienced or faint at heart.

When acquiring such a rectangular or square watch, it is important to ensure the case shows no wear, no fatigue cracks and no pinholes, particularly around the hinge and corner areas. This type of case is prone to wear and damage in these areas, which is another reason these watches are rare, as cases become beyond repair and restoration. Fortunately, this example has been extremely well cared for and very lightly used, so other than our usual careful examination and cleaning, the case has required little work apart from some very light hand-polishing. There are no scratches or dings and no damage/wear visible to the naked eye.

The case carries all the correct signatures – ‘Rolex’, ’25 World Records’, ‘Geneve Suisse’ along with ‘R.W.C Ltd’ and the sterling silver hallmark .925. On the outside of the case back it is signed correctly with the Rolex reference number 07900 and the model reference number 1491.

As always, our standard advice applies: Vintage watches should be kept clean and dry at all times.

Strap and Buckle

A high quality brown leather strap is fitted with a matching stainless stell Rolex buckle. However, if a different colour or style of strap is preferred, we will do our best to provide this at no extra charge. We carry tan, conker, dark brown burgundy and black straps in stock, in plain padded leather, alligator or lizard skin.

The Box and Papers

Although there are no original papers with this watch, the reference numbers, markings, signatures and hallmarks are all correct and indicate the date of manufacture as 1930.

Detailed particulars will be included with our purchase receipt for your interest and security. A separate insurance valuation for the replacement value of this watch will be provided at the time of sale along with our unique ‘Lifetime Authenticity Guarantee’ which states: “If this watch proves to be anything less than 100% genuine, authentic and original, a full refund will be given at any time”.

In Conclusion

This is a truly first-class example of a rare Rolex Prince Jump Hour which is ready to wear and completely practical for everyday use. If treated with care, it will make an excellent investment or heirloom piece and even though vintage gold Rolex prices have risen markedly recently, we still feel good examples such as this are still undervalued. As each year goes by and the world market for vintage gold Rolex watches continues to expand, prices will continue to climb ever higher.

A word on our prices – We always try our hardest to acquire the very highest quality watches we can find, before then restoring them to the highest possible standards. We then offer these at the fairest prices we can, taking into account our pre and post-sales care and service. This approach means we will never be the cheapest, but nor will we be the most expensive. Indeed there are some well-known stores in West London which are highly successful, charging between two to three times the price you see here. We, therefore, consider our prices to be good value and very fair, given the quality of watches we have to offer.
