I would recommend the 35mm quartz prx. The design is more cohesive and striking, with an the sharp angles playing together, vs the Seiko that is kind of a middle ground between a prx copy and any old watch. I’ve read that the prx (and similar watches) wears larger than you’d expect, so sizing down to the 35mm prx might actually be better than the Seiko’s 38.5. I see quartz prxs lightly used going for under 300 USD commonly, so the price should be similar to the Seiko as well.
