Selection of vintage-style wristwatches

A collection of three wristwatches, primarily shown from the case back side. The primary watch being held has a round stainless steel case back with a cushion-style base metal bezel. It is attached to a black leather-style strap that appears to have been repaired with white twine or thread. The case back bears several inscriptions: 'STAINLESS STEEL CASEBACK', 'JAPAN MOVEMENT', 'BASE METAL BEZEL', 'A126-04', '2143XT', and '4371'. A second watch with a brown embossed leather strap is visible, featuring a case back marked 'GENUINE LEATHER' and 'CHINA' on the strap, with additional text on the back including 'BATTERY 377', 'SR626SW', and 'WATER RESISTANT'. The third watch has a gold-tone appearance with a metallic expansion-style bracelet. All items show significant signs of wear, including scratching on the metal surfaces and fraying or deterioration of the strap materials. These watches are consistent with late 20th-century mass-produced quartz timepieces. Without inspection of the dials and internal movements, these attributions remain hypotheses based on visible markings and stylistic features.

Based on my visual analysis of the provided image, I am examining a collection of three mass-produced quartz wristwatches. I must treat the markings visible—such as the 'Japan Movement' and 'Stainless Steel Caseback' inscriptions—as hypotheses rather than confirmed origins, as I cannot verify the internal mechanical components or the legitimacy of these stamps from a photograph alone. The primary piece shows significant signs of wear and a rudimentary repair with white twine, which drastically reduces its secondary market appeal. The other two pieces, including a gold-tone expansion band watch and one with a 'Genuine Leather' strap from China, appear consistent with high-volume, budget-tier consumer timepieces from the late 20th century. My valuation range of $10 to $30 reflects the general market for 'as-is' vintage quartz watches of this grade, which are typically sold as parts, repair projects, or low-cost 'junk drawer' lots. The value is suppressed by the heavy scratching, visible plating wear, and the material degradation of the straps. To confirm any higher value, a physical inspection would be required to examine the dials and ensure the movements are functional and free of battery corrosion. If these were found to be by a more sought-after designer brand hidden beneath the case back, the value could increase slightly; however, in their current 'in the style of' mass-market condition, they function primarily as decorative or utility items with negligible collector demand.
