✅ Fits
These are generic round acrylic replacement crystals, matched by diameter rather than by watch model — they fit any round-cased wristwatch, vintage or modern, that originally took a round acrylic crystal with a friction/snap-fit bezel opening between 27.8mm and 32.4mm. This covers a large share of men's vintage watches from the 1950s–1980s, including Accurist, Citizen, Seiko, Rotary and other similar makes. Simply match the size to your case's bezel opening before fitting.
⚠️ Please check your existing crystal or bezel aperture measures within the 27.8mm–32.4mm range before ordering, and that your watch uses a friction/snap-fit round crystal rather than a tension-ring, sapphire, or non-round (cushion, rectangular, tonneau) type — this assortment isn't suitable for those.
