The Shell Star Black Tag is beautifully designed with its iconic orange indexes and comes in two different color options. It is available with a monochrome black dial or vibrant orange dial to suit your stylistic needs. The dial is clean and extremely easy to read with highlighted luminescent hour markers and luminescent hour and minute hands and an orange seconds hand.

While the second hand can be heard in the silence of the night from its resting place on a night stand, it’s not a disturbing tic, tic, tic sound. It’s a small consideration, but a pleasant realization nonetheless.

This diver’s watch exceeds the standard ISO 6425 for professional diving watches and is equipped with a screw down crown that guarantees resistance to humidity and water over the long term. This watch is also protected from damage caused by expanding helium molecules that leads to internal overpressure. This is thanks to an integrated helium valve that allows for these molecules to escape.


Do we recommend it?
