Serica 5303 Enamel Black Owner Review : Innovative, symbolic and adventurous

This is the watch I chose for my graduation gift. Technically speaking, nothing to complain about: As for the movement, nothing to complain about. It's the Soprod M100 based on the Seiko 4L movement, which is a high-end movement. The movement has been proven reliable by Soprod over time. I would have preferred a Sellita SW300, however, as it's a more widespread movement, meaning a better chance of long-term availability. It's a true tool watch: resistant to magnetism thanks to a soft iron case (bravo, Serica), water resistance to 300 m, materials resistant to life's hazards (sapphire + ceramic), screw-down crown. All this within very compact dimensions. And the icing on the cake: COSC certification. Aesthetically: It's unlike any other; it's a stroke of genius on Jérôme's part. I never tire of it. The bezel allows you to track a second time zone without the watch complication. Flaws: The biggest flaw of the watch is the bezel, which is difficult to turn. I took it to the after-sales service, and they lubricated the bezel gasket, but after a few months the problem returned. It's a shame to have a beautiful bezel with a great click if it doesn't turn. I think luminescence isn't its strong point. It's a shame this extreme approach didn't encourage them to apply Super Luminova X1. The last flaw is that you have to tighten the crown firmly, otherwise it unscrews. The problem is that there's a matte effect; the case warps due to the high tightening pressure. I think they should add a shoulder to the case at the crown. Without these flaws, I think it would be the perfect watch. Hopefully, the price stays the same.
