By the end, you’ll be a Seiko caliber 4R35 vs 4R36 expert, ready to choose the perfect movement for your next timekeeping adventure.
A Legacy of Speed: Unveiling the History
Seiko, a name synonymous with Japanese watchmaking excellence, has a rich history of innovation. In 2011, they introduced the caliber 4R35, an upgrade to the popular 7S26 movement. This upgrade brought several welcome features, including hacking (the ability to stop the second hand for precise time setting) and hand-winding functionality. The 4R35 quickly became a mainstay in many Seiko automatic watches.
In 2019, Seiko launched the caliber 4R36. This movement essentially took the 4R35 formula and added a day-date complication at the 3 o’clock position. While some minor technical differences exist (we’ll explore those later), both calibers share a core foundation, making them close cousins in the Seiko family.
Under the Hood: A Technical Breakdown
Now, let’s get down to the nitty-gritty and dissect the technical details of these two calibers.
Movement:
Type: Both the 4R35 and 4R36 are automatic or self-winding movements. The wearer’s everyday motions provide the energy to power the watch, eliminating the need for frequent battery changes.
Jewels: Here’s a slight point of difference. The earlier 4R35A version has 23 jewels, while the later 4R35B and the 4R36 boast 24 jewels. These jewels act as friction-reducing bearings within the movement, contributing to smoother operation and potentially longer lifespan. However, the difference in one jewel is unlikely to be a deal-breaker in terms of real-world performance.
Power Reserve: Both calibers offer a respectable 40-hour power reserve. This means the watch will continue to run for approximately 40 hours after it’s been removed from your wrist and the automatic winding mechanism stops functioning.
Materials and Construction:
Seiko utilizes high-quality materials in both movements, ensuring durability and reliability.
Mainspring: A robust mainspring stores the energy generated from your movements, powering the watch’s functions.
Escapement: This critical component regulates the release of energy, ensuring accurate timekeeping. Both calibers likely utilize a traditional Seiko three-pin escapement.
Anti-shock System: Seiko incorporates a proprietary Diashock shock absorption system to protect the movement from everyday bumps and knocks.
Functions and Features:
Here’s where the key distinction between the 4R35 and 4R36 lies:
Caliber 4R35: Offers hacking, hand-winding, and a date display at the 3 o’clock position.
Caliber 4R36: Inherits all the functionalities of the 4R35 and adds a day-date display at the 3 o’clock position, providing both the day of the week and the date.
If you value the convenience of a day-date complication, the 4R36 might be the clear winner. However, if a cleaner dial aesthetic with just the date display is your preference, the 4R35 could be your ideal choice.
A Matter of Style: Design and Aesthetics
While the movements share similar technical DNA, the overall design of the watches they power can vary greatly. Here are some elements to consider:
Dial Design
Seiko offers a vast assortment of dial designs across their automatic watches, catering to diverse tastes. You’ll find everything from classic and minimalist dials on dress watches to sporty and bold designs on divers.
The presence or absence of a day-date window might influence your choice depending on your preference for dial symmetry or the added functionality of a day display. Ultimately, the dial design is heavily influenced by the specific watch model you choose, not solely by the caliber powering it.
Case and Bracelet:
Similar to the dial design, the case and bracelet options vary significantly across Seiko’s automatic lineup. You’ll encounter a range of materials, including stainless steel, titanium, and hardlex crystal for the case, and options like stainless steel bracelets, leather straps, and even silicone rubber straps for added comfort and water resistance. The caliber itself won’t dictate the case and bracelet materials, so explore the specific watch models that pique your interest to see what design elements resonate with you.
Brand Image:
Seiko enjoys a well-deserved reputation for robust, reliable, and oftentimes, unpretentious timepieces. While some higher-end Seiko models boast impressive finishing and intricate details, the core brand image leans towards functionality and value. This is important to consider, especially if you’re looking for a watch that prioritizes performance over luxury aesthetics.
User Feedback
So, what do actual Seiko watch owners think about the 4R35 and 4R36 calibers? Here’s a breakdown of some common user experiences:
Accuracy: Both calibers are generally praised for their decent accuracy, typically running within +45 to -35 seconds per day. This falls within acceptable ranges for everyday wear.
Reliability: Users appreciate the durability of these movements. With proper care and maintenance, they can last for many years.
Automatic Winding: The automatic winding mechanism on both calibers is generally considered effective. Most users report the watch winds sufficiently with everyday wear.
Hacking and Hand-winding: These functionalities offered by both calibers are well-received, allowing for precise time setting and a more interactive experience with the watch. (Note: This applies only to the 4R35B and 4R36, as the earlier 4R35A lacked hacking.)
Day-Date Functionality (4R36): Users who opt for the 4R36 generally find the day-date complication convenient and practical.
Overall, user feedback for both calibers is positive, highlighting their reliability, functionality, and good value for the price.
Common Problems
While generally robust, no movement is immune to potential issues. Here are some common problems Seiko 4R35 and 4R36 owners might encounter:
Loss of Accuracy: Over time, any mechanical watch can experience a decrease in accuracy. Regular servicing by a qualified watchmaker can help mitigate this.
Automatic Winding Issues: In rare instances, the automatic winding mechanism might not be as efficient, leading to the watch stopping if not worn regularly. Consulting a watchmaker can diagnose the cause.
Date Change Issues: Occasionally, the date display might not change properly at midnight. Consulting the watch manual for proper date-setting procedures can often resolve this issue.
It’s important to remember that these are not widespread problems, and with proper care, your Seiko automatic should provide reliable service for years to come.
