Question 1

How do I know what size watch band to buy?

Accepted Answer

Measure the lug width, the gap between the two lugs where the band attaches, in millimeters. Most men's watches use 20mm or 22mm; smaller and vintage pieces often take 16mm or 18mm. The size is almost always printed in the listing. Spring bars usually come included, but confirm it, since wider lugs need longer bars to seat securely.

Question 2

What's the difference between acrylic, mineral, and sapphire watch crystals?

Accepted Answer

Acrylic (plastic) crystals are cheap at $3-$10, shatter-resistant, and easy to polish scratches out of, which suits vintage restorations. Mineral glass at $5-$20 resists scratches better but can crack. Sapphire at $15-$60+ is the hardest and most scratch-proof, though pricier and more brittle under a sharp blow. Match diameter and dome profile (flat, single-dome, double-dome) to your bezel opening.

Question 3

How do I match a replacement movement to my watch?

Accepted Answer

Identify the existing caliber, engraved on the movement or listed by the case maker, then match the family; common quartz options include Ronda, Miyota, and Seiko-style calibers. Confirm dial-foot positions, stem height and angle, hand-hole sizes, and overall diameter (a ligne or mm spec). Note whether the listing includes hands and a dial or is movement-only, which changes the price.

Question 4

Why are watch stems sold longer than needed?

Accepted Answer

Many replacement stems ship oversized so you can trim and re-thread them to fit your exact crown and case tube. You measure, cut to length, then thread the cut end or fit a split two-piece stem. Buy a couple of spares, since the first cut is easy to misjudge. Always match the stem to your movement caliber before ordering, as profiles differ between families.

Question 5

What does a typical watch crystal cost and how fast does it ship?

Accepted Answer

Crystals commonly run $4-$15 for acrylic and mineral, and $15-$60 for sapphire, depending on diameter and dome height. Many sellers ship in 3-7 business days, while custom-cut or coated sapphire pieces can take 1-3 weeks. Order one size up and one size down if you are unsure of the exact press-fit diameter; returns on cut-to-order parts are often not accepted.

Question 6

Can I use these findings for jewelry or upcycled watch crafts?

Accepted Answer

Yes. Watch faces, links, gears, and old movements are popular in steampunk jewelry, resin art, and assemblage pieces. For wearable repairs, buy fit-critical parts (movements, stems, crystals); for decorative work, salvaged dials, hands, and link chains do the job. Check whether parts are new old stock or genuinely functional if your project needs the watch to keep time.
