Crown appears not to be original and one pusher seems to be damaged (backside).

Towards the dial's centre, just below the handstack, you'll notice a small knot graphic where you'd normally find text reading "COMPUR." This is what's known as a "Savoy knot," which is a symbol of Italian heraldry, linking this piece directly to the Italian royal family Casa Savoia, or House of Savoy. Italy's Savoyard counts, dukes, and kings were in part responsible for the country's unification in 1861, in addition to their brief stints ruling over Albania, Ethiopia, and Spain. The presence of this defining insignia suggests without question that this watch was originally delivered to the Italian market, and presented to someone related to the House of Savoy.
In the past, I've seen savoy knots on the dials of similarly configured Compaxes from Universal Geneve, along with Marina Militare chronographs from Zenith. This isn't to say that timepieces bearing such insignias on their dials are common, as I could probably count every qualifying example I've encountered on one hand, even with a couple of amputated fingers. Even though the watch hasn't aged as gracefully as one would hope, I'd still deem it one seriously cool piece.
