Silver 925
Definition
Silver 925, or sterling silver, is an alloy of 92.5% silver and 7.5% copper. The copper hardens it: pure silver would be too soft for a buckle or a case. It oxidises in air and with sweat and darkens: a patina that can be removed with a cloth, or kept. In watchmaking, it is found in vintage cases and fine buckles.
Frequently asked questions
What is SILVER 925?
An alloy of 92.5% silver and 7.5% copper, harder than pure silver. It darkens with air and sweat; the patina can be polished away or left. In watchmaking: period cases and buckles.
Does a silver 925 buckle suit an everyday strap?
It suits it, but it asks for care: silver scratches and darkens more than steel. For a strap worn every day I recommend stainless steel; I see silver on an evening strap or on a period watch with a silver case, where the tone needs to match.
How do I match a strap to a silver 925 case?
I meet silver in the case and the buckle, not at the bench: I work the leather. Silver cases are almost always vintage and small: thin leather, warm colours, tone-on-tone stitching. Silver or polished steel buckle, never gold-plated.
