Otacon,

Esses relógios têm um anel em torno da máquina, dentro da caixa, que o tornam refratários ao magnetismo.

São realmente diferenciados e entregam ao consumidor aquilo que vendem.

Todo esse acabamento joga o preço nas alturas.

Os Raimaster foram recentemente reeditados, em pequena tiragem, na linha Seamaster. Segue abaixo o descritivo (em inglês) do site da Omega.



The 1957 OMEGA Railmaster

The 1957 OMEGA Railmaster was designed especially for scientists, technicians, electricians and people who needed to work close to powerful electrical fields.

It had a double case which formed a shield against magnetic fields higher than 900 Oersteds (abbreviated Oe), the unit of measurement for magnetic field strength. By way of comparison, conventional anti-magnetic watches offered protection against the influence of magnetic fields with a strength of up to 60 Oe.

Its movement, an OMEGA calibre 30 SC T4-284, was protected by the unique double case construction. The outer case was made of stainless steel, with a polished and bevelled bezel, polished solid enveloping lugs, a reinforced crystal and screwed case back with an O-ring gasket.

The inner case consisted of an “Armco” dome, a casing ring and a one millimetre thick dial made of a soft iron called “mumetal” which meant that the movement sat in a “Faraday Cage” and was shielded from magnetic influence.

The case and dial of OMEGA’s contemporary Seamaster Railmaster Chronometer bear strong resemblances to those of the 1957 Railmaster but there are some key differences inside the watch case. The Seamaster Railmaster Chronometer is powered by and OMEGA Co-Axial calibre 2403 working in concert with a free sprung-balance without index. The combination of these two elements makes the Co-Axial calibre 2403 a high precision chronometer with stable accuracy over long periods of use.

The Seamaster Railmaster Chronometer features a domed scratch-resistant sapphire crystal and its transparent case back makes it possible to monitor the precision performance of the Co-Axial movement.

The Seamaster Railmaster Chronometer is water resistant to 150 metres (500 feet)
