QC should verify the deep-blue gradient and dial alignment, then inspect the 41.0mm case edges, bezel finish, bracelet articulation, and micro-adjustment fold-over clasp. Those checks protect the two reasons this 5811 earns its place: its larger scale and its more adjustable bracelet fit.
For a buyer moving between these two references, the decisive check is simple: hold the 41.0mm outline against the wrist images and decide whether the extra presence improves the intended rotation. Then use the clasp views to confirm that the micro-adjustment hardware is part of the appeal, not just a line in the specification list.
Fit should be judged from the side and wrist images, not only from the front. The 41.0mm case and 47.5mm lug-to-lug record give this reference a broader presence than the 40mm 5711/1A-010, while the micro-adjustment clasp gives the bracelet another practical point of difference. If those two changes are wanted, the deep-blue sunburst becomes a coherent part of a larger, more adjustable configuration rather than an isolated color choice.
