What You Should Know

• Authenticity:Genuine product guaranteed.
• Vintage Expectations:These are historic artifacts, often decades old. While we ensure they are running beautifully, a vintage movement cannot be expected to match the pinpoint accuracy of a modern contemporary watch. Original parts age naturally, and any servicing is meant to preserve the watch\'s mechanical soul, not return it to a factory-new state. This authentic, lived-in character is exactly what makes vintage horology so incredibly rewarding!
• Customs & Import Duties:Import duties, taxes, and charges are not included in the item price or shipping cost. These charges are strictly the buyer\'s responsibility. Please check with your country\'s customs office to determine what these additional costs will be prior to purchasing.
• Box/Papers:Aftermarket box provided. No original papers.
• Water Resistance:As with all vintage watches, water resistance cannot be guaranteed. We strongly recommend avoiding contact with water.
