Rolex Day-Date Eisenkiesel

Meet the watch that ended up on so many presidents' wrists it got named after them. The Day-Date spells the full day of the week across the top of the dial, and it's only ever come in gold or platinum, never steel, which is a big part of why it reads as pure boardroom. The "President" name comes partly from the bracelet it launched on and partly from the world leaders photographed wearing it over the years. Dials go from quietly conservative to full-on stone and color if you want to make a statement. It's Rolex at its most formal and, comfortably, the most you'll spend to get in.
