For things like an Apple Watch case esp in dlc no advantage at all. It scratches easier. for industrial equip and implants it’s superior etc due to strength to weight ratio and Corrosion resistance. some watch manufactures like it due to the cool name. Rolex won’t touch it. It’s definitely a novelty.
What are the positives are Ti over steel? Ti is more lightweight. Ti is more resistant to rusting than steel? Ti holds a sharp edge better than steel? I don't know, just asking.
