Mechanical Watch Movement

I went to a watch exhibition last weekend and spent 20 minutes looking through a loupe at the movement of a mechanical watch. The balance wheel oscillating back and forth 8 times per second, the escapement clicking through its teeth. Every gear connected to every other gear through a chain of precision that starts with a coiled mainspring and ends with the second hand sweeping around the dial. Craftsmanship is absurd in the best sense because a Seiko SKX007 at $250 and a Grand Seiko Spring Drive at $5. 000 and a Patek Philippe perpetual calendar at $100,000 all use the same fundamental mechanism of stored energy released through regulated oscillation. Difference between them is tolerance, finishing, and complications. I like that a mechanical watch runs without a battery because the daily act of winding the crown or the motion of your wrist keeps the mainspring tensioned. That self-sufficiency means the watch functions as a closed system that only needs a human to keep it going. Finishing on high-end movements is where the craft becomes art because the Geneva stripes on the bridge plates, the beveled edges catching light. Blued screws heated to exactly 290 degrees are choices made for an audience that will look at the movement through a caseback sapphire crystal.
