It is not commonly known that Jaeger-LeCoultre, in addition to producing movements for all its own watches, has also produced movements for many other famous watch houses, such as Vacheron & Constantin, Audemars Piguet, and IWC. Indeed for most of the 20th Century, Jaeger-LeCoultre even supplied bare movements to the great firm of Patek Philippe. Then as now, Jaeger-LeCoultre has always been considered one of the very finest watchmakers in Switzerland and so of course, the world.

Since the founding of Jaeger-LeCoultre in 1833, the company has had a very inventive history, developing over 1,249 mechanical calibres, registering over 400 patents and playing a tremendous role in the development of the industry as a whole. Whether it is the winding crown, i.e. keyless watch, Calibre 101, or the iconic Reverso, it would be difficult to imagine a historical account of watchmaking without the mention of Jaeger-LeCoultre.

The company has always been a true ‘Manufacturer’ of the finest quality watch movements. This is unusual because more often than not, high-end brands such as Rolex, Patek Phillippe, Audemars Piguet and Vacheron & Constantin would often buy in movements for particular needs. For example, in 1967 when Patek Phillippe, Audemars Piguet and Vacheron & Constantin needed an ultra-thin automatic movement, it was to Jaeger-LeCoultre they turned, to produce one for them. Furthermore, the exquisite Jaeger-LeCoultre Calibre 920 is still in production and in use today by both Vacheron & Constantin and Audemars Piguet.


Here we have a superb example of a gentleman’s classic 1940s, 18ct yellow gold dress watch from Jaeger-LeCoultre with an oversize 35.5mm case and wonderful dial, complete with ‘spearhead’ hour indices and ‘Dauphine’ hands. This watch has a very highly regarded Cal.450/4C movement which is in sparkling condition and very accurate and reliable, making this the perfect watch for evening wear or with care, everyday use. As with all of our watches, this watch is in fully restored condition and will be sold with our 12 month warranty and Lifetime Authenticity Guarantee.

The Dial

This large dial comprises of applied numerals at 3 – 6 – 9 – 12 and applied gilt ‘spearhead’ hour indices, matched with original ‘Dauphine’ hands in yellow gold – all the height of elegance and complementing the gold watch case beautifully.

This is the classic 1940s and early ’50s Jaeger-LeCoultre dial, here in ivory-cream and framed by a minute rail track register. The dial is simply signed ‘Jaeger-LeCoultre’ and the overall look, as with all vintage Jaeger-LeCoultre watches, is one of classic simplicity and elegance.

This is the original dial which has previously been restored to a very high standard, although it does show some slight signs of ageing in the form of some very gentle and even fading and some very light freckling.

The Movement

The watch is complete with its all original, ultra high quality, 17 jewel, Calibre P450/4C hand-wound movement. These movements are very highly regarded as one of Jaeger-LeCoultre’s highest quality hand-wound calibres. Indeed, it qualifies as one of the best hand-wound watch movements ever produced.

The movement has been fully overhauled and serviced by our watchmaker. This involves complete dismantling to each of its component parts, ultrasonic cleaning, microscope inspection and replacement of parts as required, only with new JLC originals, then careful reassembly and oiling ready for final testing and careful calibration. As can be seen in the images, the movement is in superb condition.

The movement is signed ‘Jaeger-LeCoultre’ and ‘Swiss’ with the calibre number P450/4C and the movement serial number 442310, dating the year of manufacture to 1946.

The watch is now running perfectly having been calibrated and timed at +7 seconds per day which is truly outstanding for any watch of this age! The watch has a runtime of 43 hours from its fully wound state which shows the movement is particularly strong and running well within expected parameters. It is now ready for many more decades of faithful service and we are therefore more than happy to offer this watch with our 12 months’ warranty* and to assist with servicing again in around three years time.

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

The Watch Case

The 18ct yellow gold watch case is the much rarer oversize at 35.5mm in diameter, excluding the crown. This is considered an oversize case as typical Jaeger-LeCoultre watch cases sizes were 33mm at the time this watch was made.

The case is a superbly made two-piece case, designed for increased dust and moisture protection. It has a thin bezel and beautiful teardrop lugs which add elegance and simplicity to the watch and is in excellent condition. The watch has just received a very gentle and sympathetic clean and polish as the watch has obviously been very well cared for and there are no dings, scratches or other marks visible to the naked eye.

Inside the case-back, all is properly marked and as expected with Swiss 18ct hallmarks. Externally, the case carries the serial number 404648. This external case number is clear, indicating the watch case has not been over-polished. Importantly, the case-back is of full thickness and has never been engraved.

Please note – our standard advice applies: vintage watches should be kept clean and dry at all times.

The Strap & Buckle

A new, high quality brown lizard strap has been fitted, along with a plain gold-plated buckle. We feel the strap suits the watch very well, however, if a different colour or style of strap is preferred, please let us know and we will do our best to oblige free of charge. We carry tan, conker, dark brown and black in stock in plain padded leather, crocodile skin or lizard skin. We can also obtain most types and colours from our partners at ‘Watch Obsession’ within 48hrs. Please take a look at their huge range of 17mm straps if you wish here.

Box and Papers

Although there are no original papers with this watch, the reference numbers, markings, signatures and hallmarks are all correct, dating this watch to 1946.

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”.

A high quality hardwood presentation box is included in the sale.

In Conclusion

This is exactly the kind of watch we love to find, polish and offer to you for sale. It is many more times more stylish than the modern equivalent watch and even though it is now over 70 years old, it is still completely fresh, reliable and practical to wear as your everyday watch, should you wish. However, mostly it is a thing of beauty, some would say, a piece of art from one of the most prestigious names in Swiss watchmaking.

Should you wish to view it this way, it is also an excellent investment and heirloom piece and as each year goes by and the world market for vintage gold watches grows ever greater, limited supply and high demand from the Far East, means prices will climb ever higher!

This is a beautiful example of a classic vintage watch from one of horology’s most famous names which if treated with care, will remain an excellent investment as well as something to use, wear, treasure and enjoy. It will provide excellent reliability as well as a sound financial investment, as long-lasting as the watch itself!

A word on our prices – We always try our hardest to acquire the very highest quality watches we can find, before 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 customer 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 fair, given the quality of watches we have to offer.

We are happy to accept PayPal as this is the quickest method of payment. However, if you would like to pay by UK cheque or by UK bank transfer we will be pleased to assist you with this and pass on a 3% saving to you.
