 Lum-Tec is often praised for their world-class lume application technique, and I think they have some of the best performing lumed dials in the business.

This isn’t an idle claim because each Lum-Tec dial has 12 layers of brightly glowing Super Luminova lume applied to it. This process is patented under the name MDV, which stands for Maximum Darkness Visibility. I suspect that this process is not the easiest to master because each layer has to be aligned precisely without error to ensure crisp edges.

What is a Bullhead Watch?

If you have never heard of a bullhead chronograph, then it’s worth explaining what these special watches are. “Bullhead” is a playful, yet almost literal description of a chronograph that has the crown and pushers in the 12:00 location instead of the traditional position of 3:00 (or even 9:00 for lefty watches). Yep, the pushers are the bull’s horns, but we have never seen a 3 horned bovine (if you include the center crown) so the analogy only goes so far.  The Omega Watch Company was one of the first to introduce this design in 1969 <–click here for more info. The Bull42 A25 is a great example of a Bullhead watch and a very good value.
