1969 Omega Seamaster "Bullhead"

Free Worldwide Insured Shipping with FedEx / Authenticity Guaranteed / 14-days Inspection Period / 1-year Warranty

The Omega Seamaster "Bullhead" was introduced in 1969 as part of the Chronostop range and was marketed mainly as drivers / rally chronograph. It was nicknamed the "Bullhead" because of the unusual design of the case - getting wider in the upper part and bearing winding crown at 12 o'clock with two pushers placed on either side it reminded collectors the head of a bull. Such an unusual configuration was aimed to ease chrono activation for car race drivers. 

This particular example is notable for outstanding all original condition. It went through carefull service by Omega in 2012 and was never worn since then. Only glass, balance wheel and few gears were replaced during the service. All replaced parts come with the watch as well as service documentation, invoice and even payment slip.

    Measuring a watch

    It is always crucial to understand the size of the watch, especially when it comes to vintage watches which are generally considered as too small in comparison with what watch industry offers today. For example, the original Patek Philippe Calatrava introduced in the 1930s was only 31 mm in diameter, while today's classic Calatrava is 39 mm. When you think about 8 mm, it doesn't seem to be a big difference, but believe it is.

    In our condition reports we normally disclose three most important parameters as follows: diameter without crown / lug-to-lug length / lug width. 

    Diameter without crown

    It is, so far, the most important measurement to understand the size of a regular round-shaped watch.It helps you to understand proportions and overall look of the watch. It is important to consider width of the bezel and color of the dial, because certain combinations may make the watch look bigger, while some other smaller. It is all very individual, however there is common understanding:

    Lug-to-lug width

    This parameter will help you to understand whether the watch is comfortable for wearing. You should compare lug-to-lug width with the width of your wrist, and if lug-to-lug width is smaller or equal, then this watch shall be comfortable.

    Lug width

    This measurement is defining what size of strap you need for the particular watch. Depending on era and manufacturer you can find watches with lug width between 14 mm and 24 mm. Most common sizes are 18 mm and 20 mm.
