My Buying Guides on Seiko 5 Automatic 21 Jewels
When I first decided to purchase a Seiko 5 Automatic 21 Jewels watch, I wanted to make sure I understood exactly what I was getting and why it’s so popular among watch enthusiasts. Here’s my personal guide based on my experience and research to help you make an informed choice.
Understanding the Seiko 5 Automatic 21 Jewels
The “21 jewels” refers to the synthetic ruby bearings used inside the movement of the watch. These jewels reduce friction and wear on the moving parts, which makes the watch more durable and accurate over time. The Seiko 5 series is known for its reliability, automatic movement, and value for money, making it a great entry point into mechanical watches.
Why I Chose Automatic Movement
I prefer automatic watches because they wind themselves using the natural motion of your wrist. The Seiko 5 Automatic 21 Jewels means I never have to worry about batteries, and it has a smooth sweeping second hand that I find very satisfying compared to quartz watches.
Key Features to Look For
- Movement: Look for the reliable Seiko 7S26 or newer 4R36 automatic movement, both featuring 21 jewels.
- Day-Date Display: One of the signature features of Seiko 5 is the day and date complication, which I find very practical for daily use.
- Water Resistance: Check the water resistance rating; most models offer at least 30 meters, but some go up to 100 meters, depending on your lifestyle.
- Case and Crystal: Stainless steel cases are durable, and Seiko often uses Hardlex crystal, which offers better scratch resistance than standard mineral glass.
- Strap Options: These watches come with either stainless steel bracelets, leather straps, or nylon bands. I chose a stainless steel bracelet for versatility and durability.
What to Consider Before Buying
- Size and Fit: The Seiko 5 watches typically range from 37mm to 42mm in case diameter. I tried a few on to see what fit my wrist comfortably without feeling too bulky or too small.
- Style: The Seiko 5 comes in a variety of dial colors and designs — from classic black and white to vibrant blues and greens. Think about whether you want something understated or a piece that stands out.
- Budget: One of the best things about Seiko 5 is its affordability. You can find great models under $200, which is perfect if you’re just getting into automatic watches.
