About us

Who we are

The company was founded by Simon Stern partnered with team of experienced watchmakers and instaurators in the beginning of 2014 under controversial brand "Watchsmuggler" focused on younger audience of aficionados just entering the world of watch collecting. With growth of the audience and demand the venture was renamed to more conservative "VintageCaliber". Being fervent watch collectors and enthusiasts ourselves, we welcome the opportunity to share our expertise and knowledge, and to provide our unique professional service to other watch collectors.

Simon Stern

Being interested in watches since childhood Simon turned his hobby into profession after he received degree in law, then linguistics, and began his career in boutique law firm. Sudden change was caused by fateful meeting with big German vintage watch dealer. This meeting resulted into moving to Munich and teaming up for a new online venture. Finally  inspired and driven by idea to create a brand which will differ from many old-fashioned dealers stuck in the 90s, Simon created and developed VintageCaliber.com.

    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.
