1.5mm Domed Flat Bottom Mineral Watch Crystal 1.5mm Thick 23–50mm Single Dome

What This Is

A round, 1.5mm single-dome mineral glass watch crystal with a flat bottom (plano-convex profile). The top surface is gently domed; the inside face is completely flat. Edge thickness is 1.5mm; centre (apex) thickness is approximately 3.1mm. Available in diameters from 23mm to 50mm in 0.5mm increments — please select the diameter you need.

Each crystal has a polished, bevelled top edge for a clean, finished look once fitted. The domed profile provides a small magnifying effect on the dial beneath.

Specifications

• Material: Mineral glass
• Profile: Single dome (flat bottom / domed top) — plano-convex
• Edge thickness: 1.5mm (±0.05mm) We have other thicknesses available
• Centre thickness: ~3.1mm
• Diameter range: 23mm – 50mm (0.5mm increments)
• Edge finish: Polished bevel

Compatibility

This is a generic aftermarket blank crystal suitable for a wide range of wristwatches. It can be fitted using crystal cement (adhesive) or pressure-fit into a nylon or rubber crystal gasket, depending on the case design.

• General replacement for round watch cases accepting a 1.5mm-edge domed mineral crystal in the 23–50mm diameter range
• Suitable for many Seiko and Citizen models using a mineral domed crystal in this thickness — verify your case opening diameter before ordering
• Compatible with Fossil and similar fashion-watch cases using glued or gasket-fit round crystals
• Indicative fit for some Bulova models in the 35.5–42mm diameter range (based on aftermarket cross-reference — verify case opening before ordering)

Important: Diameter is the critical fitment dimension. Measure your case opening carefully before selecting a size. The 1.5mm edge thickness is greater than a standard 1mm crystal — this is normal for a service replacement in this profile and does not affect fitment in most cases.

Notes

• This is a generic aftermarket crystal, not an OEM part
• The domed top will produce a slight magnifying effect on the dial
• Not acrylic/Hesalite — mineral glass only
• Not double-domed — flat on the underside
• Can be cut to size if required (watch repair bench only)
