Care, use, and practical tips

Because this is not water resistant, avoid exposure to water and moisture, and wipe the case and bracelet with a soft cloth after wear to preserve the gold-tone finish. Store separately from other metals to minimize scratching. If you’re wearing it daily, consider a professional polish every few years to refresh the plating’s luster. Given its vintage status, treat the watch as a collectible piece—handle with care and enjoy its unique story on your wrist.
