What’s the Seiko Samurai SRPB51 known for?

The most famous part of the Seiko Samurai is perhaps the name of the watch itself.

The Seiko Samurai was first introduced to the public in 2004. However, it took only a few years before Seiko stopped manufacturing the Samurai because it wasn’t getting as much attention as the company expected.

But due to the insistence of diving enthusiasts and watch collectors, Seiko released a re-imagined version of the Samurai under the “Blue Lagoon” color scheme. Only 6,000 pieces of this limited-edition model were produced, and all had been sold out in a matter of days.

With the resurging interest in the model, Seiko decided to produce a full line of Samurais in different color schemes.

Whether you’re a professional diver or a casual user, the Seiko Samurai will surely satisfy your preferences. The watch isn’t boring and is a standout even among dive watches.

Design and Movement

The Seiko Samurai measures 44mm wide and 13.5mm thick. It has a standard stainless steel case usually used by watchmakers. It’s quite large, but that’s usually the case with heavy-duty dive watches like this.

It has a solid, screw-down case back and a hobnail crown, both contributing to the 200-meter water-resistance rating of the timepiece.

The crown has a diamond texture pattern which is more attractive compared to the usual ridged pattern found on Seiko diver watches.

As a standard for dive watches, the Seiko Samurai has a unidirectional bezel made of stainless steel. The first 15 minutes of the bezel has a grey insert to emphasize the decisiveness of this period for divers. The bezel has a combination of index and Arabic numeral minute markers, and a luminous triangular pip at the 12 o’clock position.

The dial features a Clou de Paris grid pattern that gives the watch a sophisticated, three-dimensional look. The index hour markers are expertly cut out and are filled with luminescent substance. At the 3 o’clock position, you’ll find the date window in white background and black text.

The designs of the hands of the Samurai perfectly befit the name of the watch: there’s the spear-tipped second hand, the sword-shaped minute hand, and the arrowhead hour hand. All the hands have a luminescent coating, making them easily visible at night and underwater.

Everything on the dial is covered with a shatter-proof Hardlex crystal. The crystal is a smudge-magnet, but considering its sturdiness and the price of the accessory, it’s the perfect fit for a utility diver watch.

The Seiko Samurai houses a 23-jewel 4R35 automatic movement, beating at a rate of 21,600 vph. Aside from the date complication, this movement also allows hand-winding and second-hacking features. Add to that the 41-hour power reserve, and you have a timepiece that’s a level above your average automatic watches in the mid-range market.

The SRPB51, which features a black and grey color combination, is one of the bestsellers among the Seiko Samurai color variants.

Samurai SRPB51 Features

Here are some points to consider that will help you decide whether you should buy the Seiko Samurai or not.

Durability

The Samurai has a highly durable build that can withstand bumps, scratches, and drops.

According to a hiker, he accidentally slipped while climbing and he slammed a portion of the bezel on a rock. After careful inspection, he was surprised that there wasn’t a scratch on the watch. He wasn’t even able to find the bumped portion because every inch of the Seiko Samurai looked the same as if nothing happened.

Comfortability

The Samurai’s lugs are relatively thin compared to other dive watches, giving it a more compact appeal despite its bulky case size. It’s your choice to have either stainless steel or a silicone strap for the bands. Sadly, the titanium option for the bracelet has been discontinued on the new releases of the Samurai model.

Accuracy

The watch gains and loses several seconds up to a minute a day. It’s not as precise as those watches found it the above-$1,000 range, but the inaccuracy is subtle and is still acceptable considering this is a sub-$500 timepiece.

Craftsmanship

The bezel markings perfectly align with the dial markers. Although this may seem nitpicking on minor details, having aligned markers is the mark of quality and superior craftsmanship.
