New rarity watch

An interesting concept of the small American company Chronodeco is created by the engineer Graig Bergsma who specializes in the metallurgical industry. The watch mechanisms are the so called NOS. It means that all the watch details excluding glass and straps have been held at the warehouses for 50 years. As the watch details were held at the warehouses during a long period of time, the collections are always limited.

The timepiece Positano, created after Bergsma had visited Italy, is done in red gold and the case diameter is 38 mm. 20 timepieces were produced: 12 with silver dial, and 8 with black one. Every model has its own number and the certificate of identity. The price is only $695.

All previous Chronodeco collections were bought up immediately and this one also won’t lie around unsold.

The novelty by DEWITT is a watch for cosmopolitans Academia Silicium Hora Mundi. The peculiarity of this watch is the second time zone operated by the button at 2 o’clock. The mechanism of the quick change is also convenient as the time indication is connected with the city indication (time zone). The automatic mechanism DW 2021 provides the 42 hour power reserve. The rotor is done in gold. The dial is made of a pure silicon plate which is 0,2 mm thick.

“SEMPRE” is the first and only watch winder for virtually any hand-wound mechanical watch. The Sempre watch winder is totally unique in concept, as it replicates the human action of fingers winding a watch crown.

The SEMPRE substitutes a mechanical finger arrangement, called a “collet”, which grasps the watch’s crown securely and rotates it. Several different size collets are provided to fit any watch crown diameter from 3 to 9 millimeters. The collet is fixed to the cylinder power shaft at the heart of which there is a ball bearing set in motion by the electric motor through the system of cog-wheels. The collet will open if you press the piston on the other side of the power shaft. The piston sets the collet on the winding crown.

Just as an individual winding senses the increasing turning resistance of the crown as the watch is being wound, the microprocessor “brain” of the SEMPRE monitors the electrical current drawn by the gear motor as it rotates. The amount of force required to wind the mainspring of a mechanical watch, known as the winding torque, increases as the watch is being wound. As the torque increases, the drive motor draws more current. The control circuit is user-adjustable to shutdown the system when it senses that the current has reached a pre-set limit, one which is well below the maximum torque that the mainspring can handle. To prevent “overbanking” the drive reverses the crown momentarily after shutdown.

For safety purposes, the drive system is fitted with a mechanical slip-clutch, which has been factory set to slip at a safe torque in the event of a microprocessor failure. This redundancy eliminates any possibility of stressing or breaking the mainspring of an expensive and, perhaps delicate, mechanical watch.

Automatically turns on every twenty-four hours. Upon actuation, the drive motor begins rotating the collet for 8 minutes. With the collet rotating at approximately 6 rpm, this provides a maximum of 48 crown rotations per day. However in practice, the actual number of rotations is controlled by the current feedback circuit whose priority is to shut down the motor based on torque, rather than by time.

Interestingly, the SEMPRE will also wind “self-winding” automatic watches.

The winding action of an automatic differs from a hand-wound mechanical in that there is a built-in slip-clutch in the mainspring mechanism to prevent over winding rather than a finite stop as in a hand-wound. In this case, the timing circuit of the SEMPRE comes into play as there may not be enough current draw increase to signal the system to shut-down automatically. Either way, this hybrid control circuit provides redundant safety for winding any type of mechanical; hand wound or automatic.

The brand Kolber will be the partner at the presentation of new Volvo C30 on the 22nd of March. The presentation will be held by the automobile dealer Musa Motors.

“New C30 is a hot car. It is oriented towards a young costumer or towards young couples who lead an active city life. The most important characteristics for them are the car design and how it is running, that’s why they will take great pleasure in driving this car”, says Fredrik Arp, president and CEO of Volvo Cars.

“We are watching the modern life with its richness and furious pace and we transfer the ideas suggested by the life itself to our watches. We are sure that it is the right way to do our job as our client deserves the best”, - claimed Rolf Wuethrich, general manager of Kolber.

Emotional design, individual style and high quality, striving for surprising and charming its admirers - the qualities that unite Kolber and Volvo C30.

The presentation will take place in the new Volvo dealer center Musa Motors on the Warsaw road.

Vodafone team, Fernando Alonso and Lewis Hamilton, became Tag Heuer ambassadors, in addition Fernando Alonso will become the “face” of the new chronograph Formula 1.

The company’s representatives have claimed that TAG Heuer watch Formula 1 experiences the second birth thanks to Fernando Alonso. The watch Monaco Vintage reproduced as the limited edition of 4 000 timepieces acquired the colours of the legendary automobile Porche-Gulf 917K. Steve McQueen was driving this very car in the film “Le Mans”. The new timepiece of TAG Heuer SLR for Mercedes-Benz (3 500 timepieces) has the design that copies the unique SLR.

The Year of Records for TAG Heuer

The company TAG Heuer has been the partner of Formula 1 since the beginning of the 1960s. It has always staked on the champions presenting its models. According to the company’s representatives the appearance of the twice world champion and up-and-coming sportsman of Formula 1 Fernando Alonso in the “star team” was the good fortune for the company.
