Watch Findings for Repair & Builds

Watch parts are fit-critical, so start with measurements. Bands list lug width in millimeters (common sizes 18mm, 20mm, 22mm); crystals are sold by diameter and dome height, in acrylic, mineral, or sapphire. For movements, match the caliber family to your dial-foot pattern and stem position, then confirm hour, minute, and second hand-hole sizes. Stems usually ship long so you can cut and thread them to a specific crown. Typical price bands: $4-$15 for crystals, $8-$30 for leather or silicone bands, $12-$45 for quartz movements (Miyota, Ronda, Seiko-style), and $20-$120+ for automatic calibers. Many sellers ship in 3-7 business days; pre-cut or custom-fit parts run 1-3 weeks. New to casing? Buy a spare crystal and an extra stem, and check whether a movement comes with or without hands and a dial.

Use the component-type filters to jump to bands, crystals, or movements, then narrow by exact size, and check the related searches for caliber families and lug widths.
