I have several Leitch clocks. These are (were?) widely used in broadcasting studios, and locked to SMPTE/EBU timecode (or mains frequency, or their internal crystal). Often available on our favourite auction site - see, for example: https://www.ebay.com/itm/123679630402 The second hand can be set to sweep or "step", but the latter is a fast sweep between seconds, and then a pause, so is virtually silent (critical for a broadcast studio!) They come in various sizes: 8 inch, 12 inch, and 18 inch. They were extremely reliable at work, and I've been delighted with the couple I now have at home.
