QC should be centered on the anniversary dial printing and alignment, bezel brushing, case surface transitions, bracelet attachment, and Nautilus clasp engagement. Those checks protect the specific reason to buy the 5711/1P and distinguish it from the blue-dial 5711/1A-010 before dispatch.
The practical buying question is whether the commemorative dial will remain the part you want to see every time the watch comes out. If yes, the 5711/1P has a clear identity beyond its shared case shape. Review the full front, angle, bracelet, and clasp sequence together so the anniversary treatment and the supporting steel finish are judged as one configuration.
The 5711/1P also rewards a deliberate comparison of the dial at different angles. The anniversary treatment should remain legible without losing the clean 40mm outline, and the bracelet should support rather than compete with it. Buyers deciding between this reference and the 5711/1A-010 should therefore look at the front and three-quarter images as a pair: one confirms the anniversary identity, the other confirms that the steel case and bracelet still have the quiet proportion expected from a 5711.
