Lan Ba · Strap II · Crown @ 3 · Cobalt Mirage
For the AP × Swatch Royal Pop Lan Ba
Cobalt Mirage
Lan Ba is one of only two crown-at-3 Royal POP models — the Savonnette layout — which means it needs Strap II rather than Strap I. Cobalt Mirage was developed specifically for this case: a vivid mid-blue that picks up the dial's small-seconds counter and the gold crown at 3.

Bioceramic · Cobalt Mirage
The colour story
Cobalt Mirage sits brighter than our Midnight Sapphire — a true cobalt pulled toward electric rather than navy. The Lan Ba dial uses the same hue, so on the wrist the case and strap read as one piece of blue with the gold crown and seconds register as the only points of contrast. Under direct light the colour shifts very slightly toward ultramarine; in shade it returns to cobalt. We left this one glossier than our other straps because the Lan Ba's Bioceramic finish is itself slightly more reflective than the rest of the collection.
Compatibility
Crown position determines strap orientation. The Lan Ba is a Savonnette layout — crown at 3 o'clock — so it takes Strap II. The octagonal holder is machined to the millimetre of the 40mm Bioceramic case; eight stainless screws fix it without touching the dial or crystal.
