The Magnificent Highlights of the Seiko Caliber 4R36

Taking a close look into Seiko’s calibers can be like walking down a road that’s constantly showing skill and improvement. The Seiko caliber 4R36, which was launched in 2019 alongside different watch models, was an eye-catcher for many watch collectors. It was for good reason, too, as the Seiko caliber 4R36 is an automatic caliber with great movement and precision.

Here are a couple of reasons why you should check out this Seiko mod part:

A Great Addition into History

The Seiko caliber 4R36 is basically an reincarnation of the 7S36 eight years before its time. It’s able to match up in terms of capabilities, especially with the addition of a day/date calendar. For reference, other Seiko calibers like the 4R35 would only have a date calendar, so that upgrade is a welcomed detail in the 4R36.

The caliber 4R36 was also a great release that can add to the richness of Seiko’s caliber releases. It’s been quite the leap since its introduction back in the 90s with the 7S26 and popularization later on in time. As Seiko transitioned from 7S into 4R and strayed away from calibers with hacking and hand winging, new investments and movements have been in place. 

Well-Priced for What It Offers

The Seiko caliber 4R36 is available in lower and middle-priced Seiko models rather than the luxury pieces the brand offers. This can come as a surprise considering that about 24 jewels and the vibrations per hour are recorded at 21,600 beats. Having more than 40 hours of power reserve is also an exceptional feature for the caliber.

It’s also notable that this caliber has the classic Diashock anti-shock system, helping reduce the damage to the balance wheel when the watch is under pressure or dropped all of a sudden. 

Present in Two Different Variants

If you’re trying to assess what Seiko caliber you have, it’s likely that you have a 4R36A. Seiko does reportedly have a second generation of the 4R36, though watch collectors may find that there’s no 4R36B to be found yet. Whatever the case, it can be exciting to await its release and see what changes it will have to the first generation caliber. 

Feature in Multiple Watch Models

As mentioned above, Seiko’s caliber 4R36 is present in more affordable models. However, there’s a healthy mix of limited editions tossed into it as well that watch collectors can look after. It also captured a lot of attention since the whole Seiko 5 Sports line watch models had featured the 4R36. 

You would still get the same performance no matter the model, especially since the caliber can be a vital part of the watch system. Recommended models with the caliber 4R36 outside of the aforementioned collection would probably be the sleek Seiko Superior Limited Edition Stargate II SRP510 Gold Tone Diver and the Seiko Blue Monster SRP455 Limited Edition.

Conclusion

The Seiko caliber 4R36 can be a showstopper. If you’re solely eyeing the caliber, checking out some Seiko mod parts might be the way to go for you.
