Review WALTHAM Nos 18s Overcoil Hairsprings Screw Head Slot Stud

The WP-77 No. 18S Waltham Overcoil Hairsprings Screw Head Slot Stud is a high-quality replacement part designed for vintage and antique Waltham pocket watches. This stud is a crucial component of the hairspring assembly, responsible for securing the hairspring to the balance wheel.

The WP-77 No. 18S is a screw head slot stud, which means it has a threaded post that allows it to be secured to the balance cock with a screw. The slot on the top of the stud allows for adjustment of the hairspring's tension, a crucial aspect of maintaining the watch's accuracy.

The No. 18S refers to the size of the stud, which is a common size for Waltham pocket watches. The "W" in WP-77 stands for Waltham, indicating that this is a replacement part specifically designed for Waltham watches.

The overcoil hairspring is a type of spring used in mechanical watches, including many vintage Waltham models. The overcoil provides additional stability and helps to regulate the watch's movement. The hairspring is attached to the balance wheel at one end and to the stud at the other, allowing it to oscillate back and forth as the watch is running.

This replacement stud is made from high-quality materials, ensuring a long-lasting and reliable fit for your timepiece. It is a must-have for any watch enthusiast or collector of vintage Waltham pocket watches. By replacing worn or damaged studs, you can help maintain the accuracy and functionality of your precious timepiece, ensuring it continues to keep time for generations to come.

1. Authenticity: These are NOS (New Old Stock) parts, meaning they are original components that were manufactured during the watch's production era. This ensures that you are getting a genuine, high-quality piece.

2. Fit and Functionality: These hairsprings are designed to fit specifically in Waltham watches, ensuring a perfect fit and optimal functionality. They are also made with the original overcoil design, which helps maintain the watch's accuracy.

3. Rarity: NOS parts are becoming increasingly rare, especially for older watches like Waltham. By purchasing these parts, you are preserving the watch's originality and preventing future wear and tear.

1. Cost: NOS parts can be more expensive than modern replacements due to their rarity and the time and resources required to source them.

2. Availability: While some online retailers may carry NOS parts, availability can be limited, especially for specific models and sizes.

3. Potential compatibility issues: While the parts are designed to fit Waltham watches, there may be compatibility issues with certain models or versions. It's important to consult a watch repair professional before purchasing to ensure a proper fit.

Buying WP-77 NOS 18s Waltham overcoil hairsprings screw head slot stud can be a great investment for collectors and watch enthusiasts who value the originality and functionality of their vintage Waltham watches.
