Adding seiko mechanism in our watches
Seiko has been around since 1881. Throughout their history, they have been known for producing high-quality timepieces that are both reliable and durable.
One of the hallmarks of Seiko watches is their in-house movements, which are often highly regarded by watch enthusiasts. Two of the most popular movements produced by Seiko are the NH70 and NH35a.
The NH70 Movement The NH70 movement is a relatively new movement from Seiko, having been introduced in 2019. It is a mechanical movement with automatic winding and a power reserve of around 41 hours.
The NH70 has 24 jewels and a frequency of 21,600 beats per hour (BPH). It is also highly accurate, with a daily variance of -20 to +40 seconds per day.
One of the key features of the NH70 is its robust construction. Seiko designed the movement to be highly durable, with a shock-resistant structure that can withstand the rigors of daily wear.
The movement is also highly accurate, thanks in part to Seiko's proprietary Spron 510 hairspring, which is known for its exceptional elasticity and resistance to temperature changes.
The NH35a Movement The NH35a movement is another mechanical movement produced by Seiko. It is similar in many ways to the NH70, but with a few key differences.
Like the NH70, the NH35a has automatic winding and a power reserve of around 41 hours. It also has 24 jewels and a frequency of 21,600 BPH. However, the NH35a is slightly less accurate than the NH70, with a daily variance of -20 to +40 seconds per day.
Despite its lower accuracy, the NH35a is still highly regarded by watch enthusiasts. It is known for its durability and reliability, thanks in part to its robust construction and shock-resistant design.
The movement is also relatively affordable, making it a popular choice for watchmakers who want to produce high-quality watches without breaking the bank.
History of Seiko Movements:
Seiko has been producing in-house movements for many years, and their movements have been highly regarded by watch enthusiasts for their reliability, accuracy, and durability.
Seiko's first in-house movement was the Seiko 5, which was introduced in 1963. The Seiko 5 was designed to be a high-quality, affordable movement that could be used in a wide range of watches.
Over the years, Seiko has continued to refine their movements, introducing new technologies and design features to make their movements even more accurate and durable. Today, Seiko produces a wide range of movements, including both mechanical and quartz movements.
Seiko's NH70 and NH35a movements are two of the most popular mechanical movements produced by the brand. Both movements are known for their durability, reliability, and accuracy, making them popular choices for watchmakers who want to produce high-quality watches.
The NH70 is the more advanced of the two movements, with a higher level of accuracy and a more robust construction. However, the NH35a is still highly regarded by watch enthusiasts, thanks to its affordability and reliability.
