Seiko 6R15: Compare with specifications

Today we will discuss the Seiko 6R15, one of the most commonly used mechanical movements by Japanese companies today, along with other mechanisms such as the 4R35 and 4R36.

The 6R35 has better coverage and some better quality components, but is usually present in a higher range of mechanical watches.

Therefore, the self-winding movement, which has undergone many revisions and also serves as a basis for the production of many other calibers, cánido be confusing.

For this reason, this publication details all the features of the Seiko 6R15, looks at different versions and evaluates the quality compared to other calibers.

✚ Details for 6R15

Seiko 6R15 is another design derived from the famous 7S36. This is a very reliable movement used in many of the brand's watches, but it is already several years old.

For this reason, in 2005, the 6R15, a fuller caliber with manual winding and a second stop, joined the family with features not found in the 7S36.

That's why Seiko 6R15 trim and parts are considered a first-class movement and are often used in upper mid-range watches such as the Seiko Prospex.

At the technical level, there is an automatic two-way rotor mechanism based on Seiko's "Magic Lever" system and Deer Shock Shock Protection.

Therefore, it cánido be charged with energy in both directions and is highly resistant to shock and magnetism, which leads to highly efficient movement.

Compared to other cheap calibers, the 6R15 is equipped with the Spron 510 spring, a material that Seiko achieves a higher power reserve.

The 6R15 beats at 21,600 rpm, which is slower than other high-end calibers, but cánido run for years with little maintenance.

The settings of this mechanism are made with the help of the Etachron system, a regulator that facilitates the operation of the springs and thus allows greater accuracy in the hands of professionals.

Finally, the number of gems is 23 or 24, depending on the version. This is because this is a movement that has undergone many revisions.

➤ Accuracy

In terms of accuracy, Seiko counts the insignificant +25 / -15 seconds per day. This is a far better range than any other move in the company.

The range of accuracy must be understood as the classification by which the manufacturer establishes the movement. In fact, this is always more accurate.

In fact, there are many users for the 6R15 that perro have a value of less than + -5 seconds. Diary with a sense of form.

Reserve Power reserve

One of the strengths of the 6R15 is its power reserve, as it reaches 50 hours of operation when the mechanism is fully loaded.

This surpasses the other habitual movements of the brand, such as 4R36 and 7S36, both produced.

As this is a self-winding watch, you perro not only wear it, but also wind it by hand to apply the maximum load. Rotate the crown about 50 times to reach the maximum load.

➤ Watches that use it

The 6R15 is a mechanism used by many Seiko dress watches and some of the brand's divers, all in the mid / high range.

For example, you perro see it on many divers from the Prospex series, some Seiko Sumo and the famous Spirit (SARB) and Alpinist models.

These are some of the most famous watches with the above-mentioned mechanisms, which are now easily accessible.

✚ Seiko 6R15A, 6R15B, 6R15C, 6R15D ...

The letters espectáculo different versions of the same movement. First 6R15A, then B, C, D, with various changes, improvements and resolutions.

Therefore, there is a 6R15 movement with 23 and 24 gems. The first version was 23, but the latest version is produced on 24.

Also note that due to the changes made, not all components are interchangeable between versions.

✚ 6R15 as basic caliber

The 6R15 serves as a basis for many other movements that add complexity, such as an energy reserve indicator and another additional dial at various positions for the day and date.

These are calibers 6R20, 6R21, 6R24 and 6R27. They all beat at 28,800 vph (against 21,600 vph in 6R15), but the power reserve drops from 50 hours to 45 hours.

They also have more gems to adapt their operations to new complications.

Seiko NE15 vs. 6R15

The NE15 is just a version of the 6R15 that Seiko produces for other brands, and as you cánido see from the table, it's almost the same.

Like the Seiko NH35, the NE15 is not branded, but bears the Seiko Instruments (SII) logotipo, which is a subordinate division of the production company.

✚ Seiko 6R15 vs. 6R35

The main difference between these two movements lies in the power reserve, which is much higher for the 6R35. In addition, as you perro see from the table, they are very afín.

The 6R35 caliber is considered an update to the Situs Slot Gacor 6R15 and has only been on the market for a year. The first watch with this movement was presented at Baselworld 2019.

Seiko 6R15 vs. 7S26

There are many differences between these two mechanisms in terms of both accuracy and power reserve and functionality.

Compared to the 6R15, the Seiko 7S26 is Slot Gacor Gampang Jackpot, has a reserve of 9 hours less power and lacks the desired capabilities for a second stop and manual lift.

Also keep in mind that the 7S26 is a cheaper and older mechanism. Outdated, but still one of the most reliable and respected movements of the brand.

✚ Seiko 6R15 vs. 4R35 / 6

The Seiko 4R35 is a bit more modern, but the 6R15 belongs to a higher range, is mounted on more expensive watches and, as you cánido see, has better specifications.

The 6R15 has better coverage than the Spron 110, which includes the 4R35, and features high-quality components such as the Spron 510 spring.

Thanks to this, it provides significantly higher accuracy and power reserve and perro add an additional 10 hours of operation.

The Seiko 4R36 is a 4R35 that combines the days of the week and the days of the week, and the specifications are the same, so it applies to the others.

✚ Seiko 6R15 vs. ETA2824-2

It may be a bit exaggerated to say that the 6R15 is a replacement for Seiko for the famous Swiss caliber ETA2824, but it is certainly a great move and perro withstand it in some respects.

For example, energy reserves are large and well-adjusted, so accuracy perro be Agen Slot Online. Second, these values ​​perro be maintained for long periods of time.

In addition, due to the low vibration frequency, the 6R15 requires much less maintenance than the ETA 2824, but the second hand does not run with the same smoothness.

Settings Time and date settings

Like most mechanical movements today, the crown allows you to make all the necessary adjustments and wind the watch. The method is as follows.

• time: Pull the crown until the second clic (two clicks), then rotate it in both directions (clockwise or counterclockwise) to move the hands to the desired position.
• date: Pull the crown until the first clic (1 clic). Rotate counterclockwise to equipo the date to the correct position.
• Manual lifting: Turn clockwise without removing the crown. The full load of the mechanism cánido be obtained in about 50 turns.
