☺ Overhauled and guaranteed to work ☺ ★★★ Genuine and Authentic Guarantee ★★★ This item was purchased by my family's watch shop at a used goods market, which only those with a used goods dealer's license can enter. I personally purchased and am now selling it. All watches have been overhauled and maintained, with every detail of the internal mechanisms checked, so you can be 100% assured of their authenticity. This is a vintage BULOVA men's manual-winding wristwatch. Although originally sold as a men's watch, its size makes it suitable for women today. The main body opens like a locket, revealing a secret compartment where you can place photos of loved ones, pets, or partners, or even a memo with easily forgotten passwords. This is a unique piece among the gold-colored rectangular watches, also known as "kakukin," which are the standard of antique American watches. The number of existing pieces is extremely small, and you rarely see one in this kind of condition. The body is gold-filled. The bezel, with its delicate engraving, beautifully reflects light. Many have been worn down and lost their gold plating, but this piece has no significant damage and is in very good condition for a watch that is over 70 years old. The dial is silver, with gold-colored hands and wedge-shaped indexes. There is a small seconds hand at the 6 o'clock position. The Arabic numeral indexes are printed to reveal the underlying gold plating. The movement is manual-winding with a balance spring. BULOVA is an American watchmaker like Hamilton and Elgin, but they had manufacturing plants in Switzerland early on. Although this is a US-made movement, its quality is comparable to Swiss-made movements. The timegrapher measurement shows a daily rate of ±15 seconds, indicating stable operation. The crystal is curved glass. The adhesive used to secure the bezel and glass had deteriorated over time, so it was re-secured with a new adhesive specifically for glass crystals. The case size is approximately 40mm in length and 22mm in width (excluding the crown). The lug width is 18mm. The space for photos is approximately 22 x 19mm. You can easily attach photos using commercially available double-sided tape like "Nice Tack" or wood glue. Except for the new leather strap and buckle, everything is original.
