Pronto watches are known for their affordable Swiss-made timepieces with a focus on sporty and classic designs. Understanding the TPD (Turns Per Day) and winding direction is crucial for maintaining these automatic watches. Here's a comprehensive guide for various Pronto models:

Most modern Pronto automatic watches have a standard TPD range of 650-800 and use bidirectional winding. This is due to Pronto's use of reliable Swiss automatic movements, often based on ETA or Sellita calibers.

When using a watch winder for your Pronto, it's generally recommended to start with 650 TPD and adjust up to 800 TPD if needed, always with bidirectional rotation to maintain optimal performance. The bidirectional setting allows the watch to wind in both clockwise and counterclockwise directions, mimicking the natural movement of the wrist.

Experimenting with TPD Settings

If you're unsure about the specific TPD setting for your Pronto watch or want to fine-tune its performance, you can experiment with different settings. Here's a step-by-step guide to help you find the optimal TPD for your Pronto:

1. Start by manually winding your watch. Turn the crown 20 to 30 times to ensure it's fully wound.
2. Place your watch in the winder and set it to the lowest TPD setting (650 for Pronto watches) with bidirectional rotation.
3. Run the winder for 48 hours, periodically checking if the watch is keeping accurate time.
4. If the watch is still keeping accurate time after two days, you've found the right setting.
5. If the watch is losing time, increase the TPD setting slightly (e.g., to 750) and repeat the 48-hour test.
6. Continue adjusting and testing until you find the lowest TPD setting that keeps your watch running accurately, not exceeding 800 TPD.

Remember that Pronto watches typically have a power reserve of about 38-42 hours, depending on the movement used. If your watch is still running accurately after 48 hours on the winder, it indicates that the winder is providing sufficient turns to keep the mainspring wound.

Additional Considerations

While experimenting with TPD settings can help you find the optimal winding for your Pronto, keep these points in mind:

• Over-winding is generally not a concern with modern Pronto watches, as they have built-in mechanisms to prevent damage from excessive winding.
• If you wear your watch regularly, you may not need to keep it on a winder constantly. Winders are most useful for watches that aren't worn daily.
• The natural movement of your wrist while wearing the watch is still the best method for keeping it wound and running accurately.
• Pronto uses various movements in their watches, including ETA 2824-2, Sellita SW200-1, and others. While the general TPD range is similar, there might be slight variations based on the specific movement in your watch.
• Some Pronto models may have specific winding requirements. Always refer to your watch's manual for precise instructions.

Remember, while using a watch winder can be convenient, it's also beneficial to wear your Pronto regularly. The natural movement of your wrist provides the best winding for your timepiece and allows you to enjoy its Swiss craftsmanship fully.

Always consult your watch's specific manual or contact Pronto customer service for the best care instructions for your particular model, especially if you have a limited edition or a watch with special features.
