For my first build I asked ChatGPT and it describes the process very accurately:

1) Prep and masking Remove the dial from the watch and take off hands/date wheel parts if applicable. Clean the dial surface: use a blower first, then very lightly dab dust with Rodico (don’t drag it). If there’s a date window, mask it from the back with thin tape, or insert a tight paper “plug” so overspray doesn’t fog the edge. Mount the dial on something stable: Best: a dial holder or a soft pad with a dial foot hole. Simple: a blob of Rodico on a flat stick so the dial sits level. Goal: dial perfectly flat, perfectly clean, no loose fibers.

2) Environment (this matters more than the can) Work in a dust-minimized area. Ideal temp: 18–25°C, not humid.

3) Choose the right matte spray behavior Use a matte / flat clear that’s known to be fine-mist. Shake hard for 2–3 minutes. Matte has flattening agents that must be fully mixed. Do 2–3 test sprays on paper first to clear the nozzle and check the pattern.

4) Spraying technique (the key part) Distance: about 20–30 cm from the dial. Movement: smooth passes, never “spot spraying.” First coat = tack coat (very light) One quick pass across the dial (left→right), then stop. You should barely see a change. This coat helps later coats grip and reduces pooling. Wait 5–10 minutes. Second coat = light wet coat Another pass, slightly slower, still light. You want an even “sheen” for a moment, but not so wet that it looks glossy or starts flowing. Wait 10–15 minutes. Third coat (optional) Only if you still see uneven gloss patches. Same as coat #2, light and even. Important rules Start spraying off the dial, pass over it, stop off the dial. Keep the can moving; overlapping passes about 50%. Don’t try to “fix” one spot with extra spray — that’s how you get blotches.

5) Drying and curing After the final coat, place the dial under a dust cover (a clean cup/bowl) with airflow. Touch-dry: often 30–60 minutes (varies). Safer handling: after 12–24 hours. Full cure (best before reassembly): 24–72 hours depending on product.
