A Closer Look at the A. Lange & Söhne 1815 Rattrapante Watch in Platinum

A. Lange & Söhne 1815 Rattrapante Watch in Platinum

The A. Lange & Söhne 1815 Rattrapante Watch in Platinum model combines two horological complications: a rattrapante chronograph and a moon-phase display. A rattrapante chronograph is a type of timepiece with two seconds hands that allow it to time multiple simultaneous events. To activate the hands, you must depress the pusher at the 2 o’clock sign. We will talk about the moon-phase display later on. The watch was first released in 2020 in Honey Gold. It had a pale yellow gold color and was only available in 100 pieces. That means few people saw the watch as it quickly sold out. As a result, people clamored for the watch, which is why the platinum version was released in 2022. With that brief description and history in mind, let us explore the features of the A. Lange & Söhne 1815 Rattrapante Watch in Platinum model.

Its Strap is Made of Black Alligator Leather

Alligator leather is generally very soft. Alligator leather is soft because alligators lack calcium in the skin. Due to its softness, you are not going to feel some extra weight on your wrist, making it one of the most comfortable materials. After wearing some watches after a while, you will begin to sweat under them. It is an unpleasant feeling when the sweat does not come off, which means you have to take off the watch. That is usually the case with metal straps, but not alligator leather straps. Alligator leather is breathable, which means that it can absorb moisture from your sweat. You will, therefore, not have to experience some wetness beneath the strap. Lastly, the material is highly elastic. Due to its elasticity, it can fit on any wrist size. Since it fits perfectly on the wrist, you will not feel pinched by it.

The Watch’s Case is Made of Sapphire Glass

Have you ever bought a watch whose glass case later scratched or broke? It likely happened after dropping it accidentally several times. Thanks to the watch’s sapphire glass case, you do not need to worry about any cracks or scratches. Sapphire does not break or scratch because it is a hard mineral. According to The Natural Sapphire Company, it has a hardness value of 9, which makes it the second hardest mineral after diamond at 10. Another reason sapphire is used in this watch is its transparency. Transparency is essential since it is what allows you to see the time on the dial. However, its high transparency means reflection will occur and cause glares on the screen. To minimize the glares, the sapphire glass is coated with an anti-reflective coating.

Water Resistance Level of 30 Meters

After looking at the header, you are probably eager to swim with it 30 meters underwater. Before you swim with it at 30 meters deep, there is a misconception about water resistance that we must address. The 30 meters measurement does not refer to the depth of water. Instead, it means the watch can withstand pressure equal to 30 meters deep. If you were to put it in a bucket full of water up to 30 meters high, and there was no water or watch movement, it would still work. However, we know that it is impossible for water to stay still.

It is easily moved by wind or people swimming. The movement of the water generates pressure that otherwise damages the watch. So, how much water can this watch withstand? According to Jack Mason, it is only resistant enough to handle water droplets from handwashing, puddle splashes from riding a bike or rain showers. So if you want a watch for swimming, consider the ones with water resistance levels of at least 50 meters. Since continual exposure to water droplets may gradually reduce a watch’s water resistance, it is advisable to have it checked or serviced regularly.

The Watch Is Controlled by a Manual Movement

The movement used in the watch is a caliber called L101.2. This caliber was made by Lange, and it is known for making attractive calibers. The caliber in this watch certainly doesn’t disappoint. It has hand-engraved Glashütte stripes on the bridges made of untreated German silver. The stripes are arranged in such a way they form a floral pattern. Other parts of the movement like the levers, jumpers and springs are polished and decorated with straight graining. You can see this movement through the sapphire crystal caseback. When you fully wind the movement, it delivers a power reserve of 58 hours. If you do not wind it after 58 hours, the watch stops running. However, if you happen to be the kind of person who habitually twists the knob for fun, you may not have to worry about your watch stopping anytime soon.

You Can Learn About the Moon Phases With This Watch

A moon-phase display shows the portions of the moon as observed from Earth at any given point. It can reproduce the moon’s orbit with a precision of 99.998%. Assuming the watch runs without interruptions, you would need to adjust the moon-phase display after 122.6 years in most watches. However, it works a bit differently in this watch. The moon-phase display uses a mechanical transmission that steps down the rotation of the hour wheel. This transmission is made possible by a product from Lange called Terraluna. Terraluna is so accurate that if this watch were to run without any interruptions, you would need to correct the moon-phase display after 1,058 years. The product uses 3 discs that absorb all the non-blue color spectra for a deep blue result.


The A. Lange & Söhne 1815 Rattrapante Watch in Platinum model does a great job in terms of aesthetics. If you buy this watch, we guarantee that you will spend some time admiring the decorated movement and black alligator leather strap. However, what you should admire most about the watch is its durability. If you do not buy a durable watch, you will spend a lot of money repairing it. With this watch’s sapphire glass case and elastic strap, you can bid goodbye to visiting watch repair shops.
