Short answer: Yes — Malaysia’s major shopping apps and marketplaces list both authentic Cartier watches (from authorised dealers and grey-market sellers) and lower-cost “Cartier‑inspired” / homage pieces. The apps to check are:

• Shopee Malaysia (large marketplace with many third‑party sellers listing Cartier-style watches and straps). (Chrono24.my)
• Lazada Malaysia (listings for Cartier watches, replacement straps and many homage/compatible pieces). (Lazada.com.my)
• Carousell / Mudah (peer‑to‑peer classifieds where pre‑owned Cartier and look‑alike watches are commonly sold). (Mudah.my)
• TikTok Shop Malaysia (growing place for fashion watches and homages — many sellers pop up there). (market trend — see major marketplaces above). (Lazada.com.my)
• Chrono24 / specialised watch dealers (for authentic new and pre‑owned Cartier through reputable listings and dealers such as Cortina and Swiss Connection). (Chrono24.my)

A note about Taylor Swift’s watch: recent coverage identifies her wearing a Cartier Demoiselle / Panthère‑style Cartier timepiece in engagement/appearance photos, which spurred interest in that Cartier model. If you want a watch “like Taylor Swift’s,” that generally refers to a Cartier square/rectangular jewellery watch (Cartier Tank / Santos / Demoiselle / Panthère family). (people.com)

Buying tips

• If you want an authentic Cartier: buy only from authorised dealers (Cartier boutiques, authorised retailers like Cortina) or trusted marketplaces that offer authenticity guarantees. (cortinawatch.com)
• If you’re buying an inexpensive “inspired” watch or strap on Shopee/Lazada/Carousell, expect homages, aftermarket straps, and sometimes unauthorized replicas — check seller ratings, return policies and images carefully. (Lazada.com.my)
• Beware trademark/consumer‑protection issues: sellers sometimes use “Cartier” in listings for compatible straps or homage designs; that doesn’t mean the items are genuine. (Lazada.com.my)

If you want, I can:

• Search specific listings on Shopee or Lazada right now (I can pull current examples and prices), or
