What makes the P.U.W. New Old Stock movements so special?
First of all, the historical value, the unique history and the extreme rarity make the New Old Stock movements by P.U.W. so special. Another peculiarity is that the in-house calibers are 100% made in Germany – there is hardly anything like that nowadays, since almost the entire production of mechanical movements takes place in Switzerland and Japan.
In the past, watch movements were primarily designed for one thing: long and precise performance. A flat design or decorative cuts that could possibly have an impact on the function were less important. That is why large-scale balance wheels and efficient winding mechanisms were used, which guarantee good functioning for years. The movements are visually appealing, but not decorated. Geneva stripes, circular graining and blue screws, which we associate with quality today, had not yet found their way into movements. In the beginning, the grindings in pocket watches were mainly used to bind the dust on the bridges. The visual benefit only came up much later.
The bidirectional winding of the New Old Stock automatic movements from P.U.W. is simply constructed and therefore enormously robust. While modern winding wheels are worn after five to ten years, the rocking bar changer lasts a lifetime here. In addition, the winding is very efficient. With 21,600 vibrations, our P.U.W. movements are among the classic ones, which is reflected above all in long maintenance intervals. In many modern movements, the escapement works much faster, which is why the maintenance intervals are shorter.
