Now a days even OnePlus, Xiaomi, RealMe, amazefit and many others offer metal casing with AMOLED screen (bigger) and have many health features in it. Many Chinese made Apple Watch Ultra 2 decoys have BP monitor, Blood Sugar, Sleep monitor, Oxygen etc…though they may not be reliable in their readings. Bringing plastic now may not attract unless the price is competitive. I also bought Apple Watch Ultra 2 clone for $40 which looks even better than the Ultra 2 49mm (curvy AMOLED Screen compared to flat one from Apple) which is completely metal (quality looks identical to Ultra 2) and able to fit all the Ultra 2 but without LTE. I went for Ultra 2 only because it lacked LTE. Now, cheaper players in my country are offering LTE (with eSIM and physical Nano SIM) with metal casing at far cheaper price points between $50-$100.
