Introduction

When it comes to Seiko movements, the 4R36 and 7S26 are two of the most popular choices among watch enthusiasts. Both movements have their own unique features and benefits, but which one is better? In this article, we will compare the 4R36 and 7S26 movements and help you decide which one is the right choice for you.

The 4R36 Movement

The 4R36 is a relatively new movement that was introduced by Seiko in 2011. It is an upgraded version of the 4R35 movement and features a hacking function, which allows you to stop the second hand when adjusting the time. The 4R36 also has a hand-winding function, which means you can manually wind the watch if it has been left unworn for a few days. This movement has a power reserve of approximately 41 hours and runs at a frequency of 21,600 vibrations per hour.

The 4R36 movement is used in many Seiko watches, including the popular Prospex and Presage collections. It is a reliable and accurate movement that is often praised for its precision and durability.

The 7S26 Movement

The 7S26 is a tried and tested movement that has been used by Seiko for over 20 years. It does not feature a hacking function or hand-winding capability, but it is an automatic movement that does not require a battery to function. The movement has a power reserve of approximately 40 hours and runs at a frequency of 21,600 vibrations per hour.

The 7S26 movement is found in many Seiko watches, including the iconic SKX007 diving watch. It is known for its reliability and affordability, making it a popular choice for those looking for a quality automatic watch without breaking the bank.

Comparison of the 4R36 and 7S26 Movements

When comparing the 4R36 and 7S26 movements, there are several factors to consider:

Precision and Accuracy

Both movements are accurate and reliable, but the 4R36 is often praised for its precision. The hacking function allows for very precise time adjustment, and the hand-winding function ensures that the watch is always running at its best. The 7S26 is also accurate, but it may lose or gain a few seconds per day.

Features and Functions

The 4R36 has more features and functions than the 7S26, including the hacking function and hand-winding capability. These features make the 4R36 more versatile and user-friendly. The 7S26, on the other hand, is more basic and does not offer any of these functions.

Price

The 7S26 is a more affordable movement than the 4R36. Watches that use the 7S26 are often less expensive than those that use the 4R36, making it a popular choice for those looking for a quality automatic watch on a budget.

Conclusion

Both the 4R36 and 7S26 movements are excellent choices for Seiko watches. The 4R36 is a newer and more versatile movement that offers more features and functions, while the 7S26 is a tried and tested movement that is known for its reliability and affordability. Ultimately, your choice will depend on your personal preferences and budget. If you want a watch with more functions and a higher level of precision, the 4R36 may be the right choice for you. If you are looking for a quality automatic watch on a budget, the 7S26 may be the way to go.
