Seiko SRPE55

Seiko SRPE55 Watch on a steel bracelet

The SRPE55 is a relatively new addition to the Seiko 5 Sports lineup. Technically, it’s a sports watch, but this particular variant is perfect for the office or more formal events like weddings, graduations, or award ceremonies. It’s affectionately known as the Dress-KX in the watch community because of its resemblance to the iconic SKX series of dive watches. However, in our opinion, this watch easily stands on its own as a great example of a modern Seiko watch.

The case on the SRPE55 is a mixture of polished and brushed surfaces. The bezel around the dial is polished on top and brushed on the side. This tapers down to a case that has polished sides and brushed lugs. When combined with the stainless steel bracelet, the Seiko SRPE55 has an elegant look that wears well on all but the largest wrists. The 40mm case size and modest lug to lug measurement are very well proportioned, while the screw-down crown at the 4 o’clock position adds comfort and gives this watch a useful 100 meters of water resistance.

The dial on the SRPE55 is similar to what you will find on other Seiko 5 Sports watches. However, when combined with the smooth bezel, it also draws strong comparisons to the Tudor Black Bay 36. That means you get a premium look for not a wallet-friendly price. The hands and indices are filled with Seiko’s proprietary LumiBrite lume. It glows long after dark and makes this watch more practical than you may otherwise think. The Seiko SRPE55 is the black dialed version, but blue, gray, and green dials are available if you prefer a splash of color.

The Seiko SRPE55 uses the 4R36 movement. It’s a strong, workhorse movement that has become the heir apparent to the venerable 7S26 in Seiko’s lineup. However, unlike the 7S26, the newer 4R36 offers both hacking and hand winding. It’s not a highly decorated movement, but it’s accurate and you can get a good look at it thanks to the see-through case back on the rear of the watch.

The SRPE55 was the second watch to be released in the revamped Seiko 5 Sports lineup, and it’s a watch that enthusiasts have been after for some time. Too many recent Seikos have been in the 42-44mm range, but this model (coupled with the newer 5 Sports SRPG range) shows that the demand for larger watches may finally be slowing. So, if you are looking for a smart, well-made dress watch that comes with spades of style and practicality, take a good long look at the Seiko SRPE55, or one of its stablemates.
