Precise

Precise timing is a precondition for aerial navigation. Every B-Uhr was tested and certified for precision by an official institute.

Readable

A rigourous and easy to read graphic dial layout were part of the official B-Uhr specifications. Immediate time reading was a must.

 

Protected

Every B-Uhr was protected against adverse effects on the balance spring, and therefore precision of a watch, caused by magnetic fields.

Pilot ready

Unheated cockpits required pilots to wear gloves. An oversized crown had the purpose of allowing easy time setting while wearing them.

Key Features

Compliant with the original B-Uhr specifications

The Watch

The evolution of the B-Uhr. A monopusher chronometer chrongraph 

Specified for purpose

Observation watches were made to aid seafarers
and pilots to navigate the sea and the air. 
They were the essence of the tool watch.

The Watch Angels B-Uhr design type complies with the 
original B-Uhr specifications.
 

Longitude

Observation watches were precision instruments that were mainly used by the military, pilots and seafarers to monitor and compare time. It's main purpose was however to help in determining position, and in particular Longitude.

 

Exact time above all

A pre-requisite to determine the geographical longitude is precise time measurement. All B-Uhr watches were tested and certified for precision by official institutes and observatories.

The Watch Angels B-Uhr is an officially certified Swiss chronometer. Each movement is tested for 15 days at three different temperatures and in five different positions (3 o’clock, 6 o’clock, 9 o’clock, dial on top, dial on the bottom) with an average daily rate tollerance of −4/+6 seconds.

 

Operational compliance

Precison was key, but to put it at use mission usability was equally important for pilots.

Time had to be perfectly readable in any condition, calling for a rigourous and simple dial layout, an oversized crown to be operated with gloves, and a stop seconds mechanism for time measurement.

The Watch Angels B-Uhr not only complies with the B-Uhr usability standards, but in many respects exceeds them and, importantly, adds day-to-day usability to a "mission grade" watch.

Identification

The logo of the manufacturer does not appear on a B-Uhr. Like any military sourced object it was identified by a certain number of identification markings

On the case-back would appear: The design type, the instrument number, the movement number and the manufacturer. On the side of the case would appear: the Specification code (FL.23883).

The Watch Angels B-Uhr is identified by the following markings: 1) Design Type: Watch Angels 2) Instrument number:  127.560 A.1 3) Movement number: SW500 MP b 4)  Specification code: FL. 23883
5) Manufacturer: Watch Angels, Mendrisio.

 

The Inspiration

The original B-Uhr Baumuster B

Historically, the observation watch was conceived and built for purpose. It was made and specified to aid seafarers and pilots to navigate at sea and in the air. Our approach has been to respect the original B-Uhr specifications but to execute them like if the B-Urh would have first been made today. With todays technology and todays aesthetic codes. 

Chronometric precision, perfect dan and night readability, anti-magnetism and an oversized crown are are all present in this 2022 B-Uhr, however the design and construction additionally take great care in assuring wearer comfort as well as fucntional and every day usability.  

We have made the B-Uhr like it would have been made today, with additional features and guaranteeing day-to-day usability and wearer comfort.

 

The origin of the B-Uhr

Project Curator
Gisbert Brunner

Gisbert L. Brunner, the curator of the project is an expert in pilot watches and the B-Uhr. He has been working on watches, pendulum clocks and other precision timepieces since 1964. During the quartz clock crisis of the 1970s, his love for the apparently dying-out mechanical timepieces grew. In the early 1980s, his passion as a hobby collector eventually led to the first newspaper and magazine articles and then to the by now more than 20 books on watches. Gisbert Brunner is the co-founder of Uhrenkosmos.

As project curator Pilot watches and  B-Uhr expert, Gisbert Brunner has worked alongside the Angels community. From the defintion of the specifications, to making sure that the original spirit of the B-Uhr was maintained and, finally, in the selection of the final design and variants. Together we answered the question: how would the B-Uhr have been made today, with todays technology and aesthetic standards?

Gisbert Brunner made sure that the historical integrity was maintained for this new "Baumuster B" type.
