Comparing any Seiko to a Rolex Oyster Perpetual is going to be a bit of a stretch, but here goes.
The OP is Rolex’s entry-level automatic everyday watch, and the brand makes a version for practically everyone, with five different case sizes on offer in 41mm, 36mm, 34mm, 31mm and 28mm.
Seiko’s entry-level automatic everyday watch is the 5 Sports SNXS Series, which debuted last year and is based on the classic affordable SNXS that was discontinued in 2019 when Seiko began revamping its Seiko 5 line.

The watch has a C-shaped 37.4mm case in stainless steel with a recessed 4:00 crown, and it features a similar dial to the Rolex OP with baton hands and indices while adding a day-date window at 3:00. At 37mm, the SNXS Series is already pretty wearable, but now Seiko has followed Rolex’s lead and expanded the line with a more diminutive version.
Shrink it, don’t pink it
Comparable in size and spirit to the 31mm Oyster Perpetual is the new Seiko 5 Sports “Hebitama” SNXS, which measures just 32mm across the case. Like Rolex with its smaller OPs, Seiko is marketing the Hebitema as a ladies’ watch, but that shouldn’t stop anyone who wants to wear one from doing so. It’s 2025; if you want to wear a 32mm watch, wear a 32mm watch.
