AP x Swatch Royal Pop: the KronoKeeper Rubber Strap and Case to Wear It on the Wrist

by Pierre-Yves in Actualités

Launched on 16 May 2026, the Audemars Piguet × Swatch "Royal Pop" collaboration caused a sensation: a pocket watch with an octagonal Bioceramic case, supplied with a calfskin lanyard to wear around the neck, on a bag or wrapped around the wrist. Singapore's tropical climate is hard on leather, and many Royal Pop owners have asked us how to wear their watch on the wrist every day. That is exactly what the KronoKeeper rubber strap + case set is for — available now at MisterChrono Singapore in seven colours at S$180.

Turn Your AP x Swatch Pocket Watch into a Wristwatch

The idea is simple: the watch slips into a rubber case shaped to its octagonal body, and a 27 × 20 mm rubber strap (27 mm at the case, 20 mm at the buckle) attaches to the case. The case protects the watch from everyday knocks while keeping a slim profile on the wrist, and the strap closes with a steel pin buckle. Your original lanyard stays untouched, so you can switch between the two in seconds.

Soft Rubber, Made for Every Day

The strap is made of soft, flexible, high-grade vulcanised rubber: waterproof, hypoallergenic, and resistant to UV, sweat and saltwater. In Singapore's year-round heat, a rubber strap simply makes more sense than a leather lanyard: it shrugs off sweat, pool water and a weekend on Sentosa, and a quick rinse is all the care it needs.

Frequently Asked Questions

Does the set fit every Royal Pop model?

The set is designed for the Lépine models of the AP × Swatch collection (crown at 12 o'clock, two hands). It is not intended for the Savonnette versions (crown at 3 o'clock, small seconds). If in doubt, send us a photo of your watch or visit our boutique at Mandarin Gallery on Orchard Road and we will check before you order.

Is it difficult to fit?

Not at all: the watch clips into the case in seconds and the strap is ready to wear. Our team can also fit it for you in store.

Is this an official product?

No. It is an independent accessory by KronoKeeper, the French premium watch accessories brand, and is not manufactured or endorsed by Swatch Group or Audemars Piguet. Watch not included.

Watch Winder Safe: the New KronoKeeper Safe for Automatic Watches

Watch winder, display tray and safe in a single piece of furniture: that is the idea behind the new KronoKeeper watch winder safe. In Singapore's constant humidity, how you store your watches matters as much as how you wear them. Fingerprint access, winders for automatic watches, cushioned trays and a humidity display — it comes in two sizes: 3 winders + 12 watches at S$2,250 and 6 winders + 24 watches at S$3,310. Why a Safe with Watch Winders? An automatic watch stops after a few days off the wrist, and you then have to reset the time — and sometimes the date or complications. A winder keeps it running; a safe keeps it protected. The KronoKeeper safe does both, with trays for quartz watches, hand-wound pieces or anything you are not wearing right now. Fingerprint Access Access is by fingerprint reader, and the drawers are operated from the touch keypad on the front. The cold-rolled steel body is covered in stitched grey microfibre leather, making it a discreet piece of furniture for a dressing room, bedroom or study. The safe is also compatible with the Tuya app. LCD Display: Temperature and Humidity at a Glance The front display shows the time, plus the temperature and humidity inside the safe. With humidity high all year round in Singapore, the built-in display showing temperature and humidity is more than a gadget: it tells you at a glance whether your collection is stored in the right conditions, ideally in an air-conditioned room. Removable Winders and Trays Each rotor has its own setting buttons and lifts out to fit the watch or for cleaning. The 12-watch trays, lined in light grey suede-like microfibre with a cushion per slot, slide out of the drawer so you can choose the watch of the day or show your collection. Two Models to Choose From KronoKeeper Watch Winder Safe – 3 Winders + 12-Watch Tray — S$2,250: 15 watches in total, 2 drawers, approx. 40 × 35 × 35 cm (H × W × D), 19 kg. KronoKeeper Watch Winder Safe – 6 Winders + 2 Trays (24 Watches) — S$3,310: 30 watches in total, large glass-front drawer with 2 trays, approx. 35 × 76 × 35 cm (H × W × D), 29 kg. Frequently Asked Questions Do the winders suit every automatic watch? Each rotor is set independently with its own buttons, so you can adapt it to each watch. If you are unsure about your movement, ask our team. What is the difference with a simple winder? The safe adds security (fingerprint access, steel body), storage for your whole collection and humidity monitoring — where a stand-alone winder only keeps two or three watches running. When is it available? Both models can be ordered now; first deliveries are planned from November 2026. Available at MisterChrono Singapore Free delivery across Singapore.

KronoKeeper aluminium watch case for 36 watches

Aluminium Watch Case for 36 Watches: Store and Travel with Your Whole Collection

Once a collection grows past twenty watches, storage becomes a serious question: how do you bring everything to a watch meet, a boutique or a safe without scratches or knocks? Many Singapore collectors travel regularly across the region, and keeping a large collection safe on the road is a real challenge. KronoKeeper's answer is an aluminium watch case with 36 slots, adjustable cushions and TSA locks — now at MisterChrono Singapore for S$740. 36 Watches on Two Removable Trays The case holds two 18-slot trays lined in grey suede-like microfibre. Each tray lifts out independently — handy for showing your collection, choosing the watch of the day or storing one tray on its own. A suede sheet sits between the two levels so watches never touch. Cushions That Adapt to Every Watch The cushions come in two sizes and work with an add-on cushion system. Combined, every slot adapts to wrist sizes from 160 to 195 mm: a dress watch on leather, a diver on a steel bracelet or a large chronograph all stay secure with the strap closed, with no movement in transit. Your Straps Travel with the Collection The lid features elastic bands that hold spare leather, rubber or fabric straps flat — ideal if you like to travel with two or three options per watch. A True Travel Case The ribbed aluminium shell protects against knocks and the carry handle makes it easy to move around. Flying out of Changi with your collection? The two TSA combination locks allow airport security to inspect the case without forcing it. At home, the case keeps up to 36 watches in a compact footprint — ideal for condo living. Specifications Capacity: 36 watches (2 removable trays of 18) Cushions: 2 sizes + add-on cushion, wrists 160 to 195 mm Shell: ribbed silver aluminium, carry handle Interior: grey suede-like microfibre Lid: elastic bands for spare straps Closure: 2 TSA combination locks Weight: approx. 5.5 kg Frequently Asked Questions Can I fly with this case? Yes. The TSA locks allow inspection without damage. For a valuable collection, we recommend keeping it with you in the cabin if your airline's size limits allow. Does it suit small wrists? Yes: with two cushion sizes and the add-on cushion, it covers 160 to 195 mm. For very short steel bracelets, use the small cushion without the add-on. Can I use it for storage at home? Absolutely — it is also a compact way to store a large collection in a cupboard or a safe. Available Now at MisterChrono Singapore The KronoKeeper aluminium watch case for 36 watches is available at S$740. Free delivery across Singapore, and you can see it at our boutique at Mandarin Gallery on Orchard Road. For collections that also need winding and security, discover our KronoKeeper watch winder safe and all our travel cases for watches.
