We have listed this watch as a men’s watch, but an increasing number of women are wearing them as astounding statement/bracelet/watch combination pieces.

Origin/Model: This movement was produced from 1956 to 1975 and is considered one of the finest hand wind movement produced by Patek Philippe.  

Movement/Mechanism: Extra Rare Authentic Patek Philippe Movement Calibre 23-300, 18 Jewels, Breguet Hairspring, Gold Giromax Balance. Calibre 23-300 is an hand wound watch movement. This is a common and respected small, thin manual movement. As the name implies, Cal. 23-300 is 23 mm (10 lignes)  in diameter and 3 mm tall. This compact size made it ideal for the popular Calatrava and similar smaller watches produced in the 1950's and 1960's.

Cal. 23-300 is classic in layout, with a barrel bridge covering the ratchet and crown wheel, a curved center wheel bridge, and separate cocks for the fourth and escape wheel. It was derived from the preceding movements but with many modifications. 

It is notable in that it is equipped with both an overcoil hairspring  and a free-spring Gyromax balance, a combination not found in any other 10 ligne Patek Philippe movement.This movement is greatly respected today, with many saying it is one of the best hand-wound movements ever produced by Patek Philippe. Carlos Perez said it "represents both the technical and artistic peak of Patek's 10 ligne handwinds, as the 27-AM-400 was the peak of their 12 lignes.

Directions: This is an antique watch. Different antique watches use different mechanisms to wind and/or set the time. If you are not familiar with these, or it is unclear to you how to wind or set the time on your particular watch please contact us for specific instructions prior to attempting wind the watch or set the time to prevent damaging the watch. 

Servicing:  This original movement of this beautiful wristwatch has been beautifully preserved, astoundingly so considering the age of the piece. The mechanism has been recently serviced to ensure it winds and sets smoothly while keeping accurate time.

Protecting and Caring For Your Watch: All antique watches are mechanical, and as such should be treated with extra care. You should be careful not to expose an antique watch to the wear and tear. This doesn’t mean you shouldn’t wear it often, or even every day. The best thing for something that is mechanical is to be used regularly. It does mean extra care should be taken not to drop it or expose it to water.

Antique watches are generally not waterproof as this technology was not in general use until the mid-20th century. You should therefore protect your antique watch from exposure to moisture.

If your watch becomes wet it should be dried as quickly as possible. This should be done using a hair dryer, opening all covers and gently blow drying the movement, dial, covers, and crown. This will eliminate or at least reduce the build up of any rust. Be careful not to turn the speed of the hairdryer up too high or hold it too close to the watch. A strong hair dryer held too close to a watch could blow a hand off the watch.

If your watch becomes exposed to salt water you should immediately spray your watch with purified water to remove all salt before drying the watch. If salt is left inside the watch it will combine with moisture in the air over time and begin to rust metal the components of the movement and other parts of the watch.

Winding any mechanical watch too tightly may break the mainspring, so be mindful of when you begin to feel resistance as you are winding your watch. Avoid winding the watch with force or aggressively. 

When you are adjusting the hands of your watch, move them in a clockwise direction only. It is possible that counter-clockwise adjustments may damage the movement. If you do decide to make counter-clockwise adjustments make them for minutes, not hours.

We recommend that every two to three years you have your watch serviced, primarily to oil the mechanisms within the movement.

If for any reason dust or dirt makes its way into the watch, allow the watch to run down completely. Don’t wind the watch again before having it serviced by a qualified watch repair expert. Dust will absorb and remove the most important lubricants and cause the movement components to wear down. 

If a need arises to clean the case, dial, crystal, etc., we advise you use a cloth that does not leave fibers as these may get caught and left behind in the movement.

Keep your antiques watch away from magnets. Strong magnetic fields may affect the accuracy of your watch since some vintage watches were made including iron-based components

Antique watches typically keep time accurately within about five minutes per day. If you experienced a various significantly greater than that, please contact us (or a watch professional for diagnosis). We see this very, very rarely with our watches, but should it occur it is not cause to be alarmed.

If you are flying a high-altitudes regularly with your antique watch you may wish to have it oiled more than every two to three years. The extreme temperature changes that accompany high altitudes can cause the oil viscosity to decrease more rapidly than usual.

The Story: Patek Philippe and Company was founded in 1851 in Geneva, Switzerland. They design, manufacture, and distribute, watches and movements in every corner of the world, and yet, the sheer expense makes a Patek a very rare watch. 

Here at Every Watch Has A StoryTM more than ninety-percent of our Patek’s (as they are affectionately referred to by connoisseurs) are even rarer as they are one-of-a-kind creations that combine antique and vintage Patek Philippe movements with modern cases.

Aficionados and experts consider Patek Philippe watches to be the most prestigious timepieces in the world. Patek Philippe is the Rolls Royce of watches. 

Antonio Patek was a polish watchmaker who teamed up with Czech-born Polish watchmaker Franciszek Czapek started making pocket watches in 1839 in Geneva in 1839. Five years later they went their separate ways and Antonio Patek was joined by French watchmaker Adrien Philippe who would become the inventor of the keyless winding mechanism. 

It was Patek Philippe popularized the minute repeater, the perpetual calendar, split-second hand, chronograph, and many of the features that became the foundations of what would ultimately evolve from pocket watches to wristwatches. 

These are the most sought after watches in the world by collectors. Patek Philippe timepieces have set record prices at every prestigious auction house in the world. 

In 1999, the company opened the Patek Philipe Museum in Geneva after restoring a building with a long history as a home to the craftsman who made Patek Philippe timepieces for more than a hundred years. 

Auction prices have been driven up in many cases by the Patek Philippe Company itself trying to acquire pieces for it’s own museum.

Their list of clients include more royalty than any other watch, and celebrities clamor for both antique and the latest Patek’s. 

Every Watch Has a StoryTM is in no way affiliated with Patek Philippe and does not claim to be. We simply love their products and make them available to our customers who enjoy surrounding themselves with the best of the best.
