Seiko SARB021 Review
My rating: 8/10. A high quality Seiko timepiece powered by a 6R15 automatic movement.
Hello, today I’m taking a look at the Seiko SARB021. This is a pretty impressive watch that’s powered by the reliable 6R15 automatic movement and is perfect for casual and formal occasions.
The SARB021 is one of Seiko’s higher-end timepieces and as such comes with more of a mid-range price tag. Sadly it’s actually quite difficult to come across them these days. I’d recommend asking around some of the bigger watch forums for some tips if you’re after one.
I hope you enjoy today’s Seiko SARB021 review.

Seiko SARB021 Technical specifications
To get things started I wanted to showcase some of the most popular specifications that people like to check up on for a new watch. This gives you the opportunity to see if you like this style of watch from the get-go. For example, some people wouldn’t want to go for a very large watch.

- Crystal Material: Sapphire crystal
- Case Diameter: 39mm
- Case Thickness: 12mm
- Movement: 6R15 Automatic

Seiko SARB021 Dial and Casing Design
The Seiko SARB021 is a popular automatic dress watch from the popular SAR collection of watches. The dial is finished in black with silver coloured hands and bar style hour markers.
On the dial at the 3 o’clock position is a date indicator which is highlighted by a silver square. There are also the terms ‘Seiko’, ‘Automatic’, and ’23 jewels’ written on the dial.
The casing of the Seiko SARB021 is made of stainless steel and has a diameter of 39mm with a thickness of 12mm.
The crown is located at the 3 o’clock position on this model and features a crown guard, note that the crown does not screw down on this timepiece.
On the rear of the SARB021 is an exhibition style caseback. This allows you to take a look at the inner workings of the watch through a glass lens that’s made of Hardlex glass.
Strap & Clasp
The strap of the Seiko SARB021 is made of stainless steel with a width of 20mm and fastens with a push release style clasp. You can change the strap if you feel like it, the gap between the lugs measures 20mm. Purchase a watch repair kit for all the tools required for this job.
The Seiko SARB021 Movement
Powering this popular Seiko watch is the 6R15 automatic movement, this is found in many SARB and SARX watch models like the SARB033 and SARB065 for instance.
The Seiko 6R15 automatic movement has a 23 jewel design and beats at 21,600 BPH. This gives you a smooth sweeping second hand movement with its 6 ticks per second vs a standard quartz that beats at 1 tick per second.
When fully wound this timepiece has an excellent power reserve of 50 hours. This movement features hacking, this means the second hand will stop movement when the crown is pulled out to the time-setting position, this allows you to set it to the second.
Seiko SARB021 Crystal
Whilst the rear exhibition caseback on this watch makes use of a Hardlex crystal glass, protecting the front of the watch is a more expensive sapphire crystal glass. Sapphire glass offers an excellent level of protection against scratches and knocks. Knowing this is a higher end Seiko watch, I’m not surprised at all to see this.
