A perpetual calendar with "practical value"

Posted by lifata on May 6th, 2023

Self-produced movement, perpetual calendar, 120-hour dynamic storage, 1500 Gauss anti-magnetic, 18K gold case, combine these keywords, you may not expect Baume & Mercier to have such a high-end work. That's right, this is the protagonist of this article: the Baume & Mercier Clifton series perpetual calendar. In our general impression, the price of Baume & Mercier watches is mainly affordable, but the price of this product is very high, far exceeding the mainstream pricing range of other watches of the brand. But it is the one I think has the most "practical value" among the many perpetual calendar models. Let me talk about my opinion.

Let’s talk about “practical value” first. We know that famous watches can be divided into collection-grade and consumer-grade. Obviously, the term “practical value” describes mostly consumer-grade products. As a watch worn in daily life, the performance of various parameters of the Baume & Mercier fake Clifton Perpetual Calendar is considered outstanding among similar watches. 50 meters waterproof and 1500 Gauss antimagnetic greatly broaden its use scenarios, especially 1500 Gauss antimagnetic is more important today when strong magnetic fields are ubiquitous.

Although the selling price is one of the reference factors for measuring "practical value", it is not absolute. In fact, the Baume & Mercier Clifton Perpetual Calendar is not the cheapest perpetual calendar watch among all Swiss brands, but it is one that I think has reasonable configurations in all aspects. If only ranked by price, Frederique Constant HIGHLIFE perpetual calendar has the lowest entry threshold, but considering that the movement has only 42 hours of theoretical dynamic storage and brand influence, its audience is very limited. Ranked above Frederique Constant, the "second easiest" perpetual calendar watch comes from the Montblanc HERITAGE SPIRIT series. However, Montblanc's MB 29.15 movement is not a self-produced movement in the full sense, but a self-developed perpetual calendar module is added to the basic movement Sellita SW300-1. The brand has not adjusted the parameters of the basic movement, and the dynamic storage is also only 42 hours. From the perspective of "practical value", the Baume & Mercier Perpetual Calendar is indeed better.

The importance of long power to modern fake watches uk is self-evident. From luxury to affordable brands, many new products in recent years have replaced movements with power storage of more than 70 hours. As for the perpetual calendar, the advantages brought by the long power will be more significant, which is also an important reason why I think the Baume & Mercier Clifton perpetual calendar has "practical value". We know that because the structure of the perpetual calendar movement is very precise, if it is accidentally stopped due to insufficient power, it will take time and effort to readjust, so the perpetual calendar watch needs to be placed on the watch for a long time. Taking the most popular high-end brand perpetual calendar watches on the market as an example, their dynamic storage is generally concentrated in 38 to 80 hours, while the Baume & Mercier perpetual calendar movement has a 120-hour dynamic storage, which has obvious advantages. At the same time, it also makes it one of the few perpetual calendars with a dynamic storage capacity of more than 100 hours.

Now that the perpetual calendar is mentioned, many watch lovers must be curious about the movement. The BM13-1975A C2 movement used by the Creighton perpetual calendar is an improved model of the current brand’s main self-produced movement BM13-1975A. On this basis, a perpetual calendar module is added, and the other parameters are consistent with the basic movement. It has high scalability, which is also the advantage of Baume & Mercier's self-produced movement.

In fact, Baume & Mercier’s self-produced movement has not been put into use for a long time. The first self-produced movement BM12-1975M in the modern sense was released in 2017 and is a manual winding movement. Then in 2018, Baume & Mercier launched the BM12-1975A self-winding movement with 120 hours of dynamic storage. It continues to use the silicon balance spring, silicon pallet fork and escape wheel in BM12-1975M, and also has a 1500 Gauss anti-magnetic ability and strong performance.

However, the BM12-1975A was not put into use for a long time, and was soon replaced by another new movement, the BM13-1975A. Subject to patent issues, the new movement cancels the silicon hairspring and returns to the traditional metal hairspring, but still retains the silicon pallet fork and escape wheel. At the same time, the upgrade of the BM13-1975A movement is to modify the size of the barrel and improve the lubricating oil. The movement is divided into a conventional version and a version certified by the Swiss Observatory, but there is no significant difference in accuracy between the two. Because even for the regular version, the brand will adjust it according to the error range of the COSC standard to ensure that the accuracy is controlled at -4/+6 seconds/day.

After talking about the hard parameters and the reasons for "practical value" in my opinion, I will focus on other aspects. There are many series of Baume \u0026 Mercier Replica Watches Toppest, covering different categories from sports to formal wear, retro to modern, but the perpetual calendar function, one of the "top complex functions", is exclusively given to the Clifton series, which is enough to reflect the important status of this series. In addition to the perpetual calendar, this series launched in 2013 also has a flying tourbillon watch (model: 10143) equipped with the P951 movement, which is the "window" for the brand to demonstrate its advanced watchmaking strength.

Baume & Mercier Clifton 10632 uses an 18K rose gold case, and the material is very gorgeous. As a perpetual calendar, its dial follows the classic layout, the month display is located below the 12 o'clock position, and a red '4' indicates leap years. The week display panel and the calendar panel are separated on the left and right sides, and above 6 o'clock is the moon phase display. Regarding this distribution method, although it is difficult to verify the earliest source (it is also said that it originated from Patek Philippe), what is certain is that it has become the most recognized classic perpetual calendar layout.
