Russian “MIG” cockpit clocks are widely available online and make a great desk clock. I recently received one for my birthday and designed this 3D printed stand for it (available free on Thingiverse). For reference, here’s a bit more about these clocks.
On the subject of unusual Patek Philippe Calatrava references, may I present a very unusual sculpted model: Ref. 5090J from about 2000, also called the “Russian Watch” due to its limited production for that market. I found two examples of this unusual reference for sale, so I thought I would take a moment to talk about it.
