Apple is reportedly planning to launch new Apple Watch models that use ceramic and titanium materials as early as next month. 

New images contained in Apple's latest watchOS beta revealed the plans for these new models that will reportedly come in 40mm and 44mm versions

The Verge reported that Spanish-language site iHelpBR spotted the references to the two smartwatch models in the latest watchOS 6 beta just a few days after spotting a potential announcement date for the iPhone 11. iHelpBR also found animations for the initial Apple Watch setup process.

Titanium And Ceramic For Apple's Smartwatch

This will not be the first time Apple uses ceramic for its smartwatch. A ceramic Apple Watch was introduced with the Series 2 and 3 albeit no ceramic version was made for the Series 4 Apple Watch. Current Apple Watch models have a ceramic back, but Apple will likely have a new high-end ceramic model.

The company has never released an Apple Watch with a titanium finish, but the company's newly-released titanium Apple Card uses the same material.

Titanium is more expensive compared with stainless steel and is not as flashy. It is also stronger, lighter, and more scratch-resistant. Ceramic is more brittle once it gets broken but it is resilient against scratches.

It is not yet clear if the titanium casing will replace stainless steel or become a new option. It is neither clear if the new materials will be exclusive to a new Apple Watch Series 5 nor these will also be offered as extra case material options for older models. Apple is known to introduce new materials alongside hardware upgrades.

Launch Of New Apple Watch Models

Company is expected to launch its iPhone 11 lineup on Sept. 10. The new Ceramic and Titanium Apple Watch models are anticipated to be part of the announcement.
