Review TIMEX Lot Of Mechanical Movements Runs Spare Parts Repair Read

The **Timex M104/M105 Mechanical Movement** is a meticulously crafted, full-power, automatic winding movement designed to deliver precision, durability, and timeless elegance to wristwatches. Engineered with a **28-jewel, 17-size** caliber, this self-winding mechanism ensures reliable performance with a power reserve of up to **40 hours**, allowing for extended wear without frequent manual winding. The movement features a **highly polished, silver-plated** rotor and balance wheel, optimized for smooth, accurate timekeeping with a **21,600 vibrations per hour (VPH)** frequency, resulting in a consistent sweep-second hand and minimal error over time. Built with **high-grade stainless steel** components, including a robust **gear train and escapement**, the M104/M105 movement is engineered to withstand daily wear while maintaining exceptional longevity. Its **modular design** allows for easy servicing and part replacement, making it a favored choice among watchmakers and enthusiasts seeking both functionality and craftsmanship. Whether integrated into a classic dress watch or a sporty diver s model, this movement delivers the hallmark Timex reliability blending affordability with precision engineering to ensure dependable performance for decades. Ideal for collectors, restorers, and watchmakers, the M104/M105 spare parts and repair components are essential for maintaining the integrity of Timex s iconic mechanical timepieces.

**Pros and Cons of Buying a Timex M104 Mechanical Watch (with M105 Spare Parts for Repairs)**

### **Pros**

1. **Affordability** The Timex M104 is one of the most budget-friendly mechanical watches available, typically priced well below $100. This makes it an excellent entry point for those new to mechanical watches or those on a tight budget.

2. **Simple and Reliable Movement** The M104 uses a basic but durable automatic movement (likely a Seiko 4R35 or similar), which is known for longevity if maintained properly. It lacks complex complications, reducing the risk of mechanical failure.

3. **Easy to Service and Repair** Because of its straightforward design, repairs are relatively inexpensive and accessible. Spare parts, such as the M105 (a common replacement movement), are widely available, and many watchmakers or even hobbyists can perform basic servicing.

4. **Durability** The case and movement are built to withstand daily wear, making it suitable for casual use. The stainless steel case resists corrosion, and the movement is designed for reliability rather than precision.

5. **Vintage Appeal** The M104 has a retro, utilitarian look that appeals to those who prefer a no-frills, functional design. It s reminiscent of classic Timex dive watches but without the high cost.

6. **Spare Parts Availability** The M105 movement (a common alternative to the original M104 movement) is widely stocked by watch repair shops and online retailers. This means you can easily replace a worn-out movement without breaking the bank.

7. **Good for Learning** If you re interested in learning about mechanical watches, the M104 is an ideal starter watch. Its simplicity makes it easier to understand basic watch mechanics compared to more complex timepieces.

### **Cons**

1. **Limited Precision** Unlike high-end mechanical watches, the M104 is not designed for accuracy. It may lose or gain a few seconds per day, which is acceptable for casual wear but frustrating for those who expect precision.

2. **Basic Design** The watch lacks modern features such as date displays, chronographs, or water resistance beyond basic swimming (typically 30 meters or less). It s purely a time-telling watch with no additional functions.

3. **Potential for Wear Over Time** While durable, the movement may wear out after several years of use, especially if not serviced regularly. The M105 spare movement can extend its life, but it s not a permanent fix if the case or other components degrade.

4. **Resale Value** Mechanical watches, even affordable ones, generally lose value over time. The M104 is no exception, and reselling it for close to its original price is unlikely unless it s in pristine condition.

5. **Maintenance Requirements** Like all mechanical watches, the M104 requires occasional servicing (every 3 5 years) to keep it running smoothly. Neglecting maintenance can lead to premature failure.

6. **Limited Customization** Unlike quartz watches, mechanical watches offer no adjustable settings (e.g., date correction). If you prefer a watch that aligns perfectly with your time zone, you may need to manually adjust it.

7. **Potential for Overpaying for Used Models** If buying secondhand, some sellers may inflate prices due to the watch s vintage appeal. Always check for authenticity and condition before purchasing.

### **Conclusion**

The Timex M104 mechanical watch is an excellent choice for those seeking an affordable, no-frills mechanical timepiece. Its simplicity, durability, and ease of repair make it ideal for beginners, watch enthusiasts on a budget, or anyone who values functionality over complexity. However, it is not a precision instrument, and its resale value is modest. If you re willing to accept its limitations and perform basic maintenance, the M104 (or a model with an M105 spare movement) offers great value as a starter mechanical watch.

### **Recommendation**

- **Buy it if:** You want a low-cost mechanical watch to learn about watchmaking, enjoy a vintage aesthetic, or need a reliable timepiece for casual use without high expectations for accuracy.

- **Avoid it if:** You require precision timekeeping, additional features (like a date function), or plan to resell it for profit.

- **Best for:** Beginners, hobbyists, or anyone who appreciates a simple, durable watch without unnecessary complications.

For those concerned about longevity, consider pairing the M104 with an M105 spare movement during servicing to extend its lifespan. Regular maintenance will ensure it remains a functional and enjoyable watch for years.
