Welcome to Stefan Vorkoetter’s web site! I’m a private pilot and model aviation hobbyist, slide rule, calculator, fountain pen, and watch collector, electronics hobbyist, Hammond organ enthusiast, and software developer living on a Fjord horse farm in Ontario, Canada. This page is a gateway to the ever growing collection of articles I like to write describing my projects and hobbies. If your interests coincide at all with mine, I’m sure you’ll find something useful here.
The selection of aftermarket dials available for customizing watches is growing steadily, but depends on the movement being used, with Seiko-compatible dials being most common. For other movements, the choices are more limited or sometimes non-existent. In the last year, I’ve undertaken three watch projects in which I was unable to buy the desired dial. The solution for each of these was a home-made dial. This article describes the technique used for two of them.

The offerings from Rolex and Tudor have never appealed to me. There are so many Submariner look-alikes out there, that there’s little to differentiate the real thing. Then, Tudor released the Heritage Black Bay. Combining a Sub case, red bezel, Rolex style dial with rose-gold framed markers and hands, they have created a watch I actually like. But not $3500 like. Buoyed by the success of my X-33 project, I decided to try creating a Black Bay homage.
Many watches have a so-called “negative” liquid crystal display (LCD), where the background is dark and the digits are light. I’ve often read complaints about them being difficult to read in less than perfect lighting conditions, and I began to wonder why. I think I’ve figured it out.
The first time I saw the Omega Speedmaster X-33 analog-digital watch, I didn’t like it all that much. I had just started collecting Russian mechanical watches and was turning up my nose at quartz watches. But a few days later, I just had to have one.
Sadly, Omega discontinued the X-33 in 2006. Used examples are available, but at prices starting around $2000, well beyond what I’m willing to spend on a watch. So, as is my custom when something costs more than I’m willing to spend, I made my own.
The watch collecting bug first bit me in late 2012, when an elegant Russian Strela (Стрела) hand wound mechanical chronograph caught my eye. Until then, I hadn’t realized affordable mechanical watches (i.e. not Rolexes and Omegas) were still available. After acquiring a Strela, I became interested in other Russian watches, began a small collection, and picked up some watch repair skills along the way.
