Serica came back with strength in 2021 when it released the 5303, the brand’s first diver. This model doesn’t look like the 4512 in any way except for the Broad Arrow handset. And while brands normally carry over their unique design language from one model to the other, Serica did not. The 5303 looks like a Serica but it doesn't look like the 4512. It’s quite strange, to be frank. But in many aspects, the 5303 is to me the better of the two models.
