Panerai Submersible QuarantaQuattro eSteel™

by Chamath Gamage

Panerai’s latest release shows that the measure of the watchmaking capabilities of a company is not confined to how sophisticated the movements are or the precision in its finishing. The Panerai Submersible QuarantaQuattro eSteel™ takes a closer look at how sustainably the timepiece can be created. To better protect the environment, watchmaking practices and the ecological impact of the process of creation need to be more thought out. This is what Panerai is focusing on with their latest release for Watches & Wonders 2022. 

Panerai states that “Panerai is committed to developing strategies for a sustainable future, including reducing waste and promoting reuse of materials. The Panerai Submersible QuarantaQuattro eSteel™ recognizes the critical importance of sustainability goals while maintaining the brand’s established design codes and technical finesse: 72g of the Submersible QuarantaQuattro eSteel™ is made of recycled materials, corresponding to 52% of the total weight of the watch (that is 137g)”.

With the use of eSteel™ on Panerai’s Submersible collection, the timepieces can still withstand the same pressure and durability as standard conventional steel. This is because eSteel™ has the same properties as conventional steel. The chemical composition is similar, with the physical structure and resistance to corrosion being identical as well. Making eSteel™ the more sustainable choice. 

The Panerai Submersible QuarantaQuattro eSteel™ comes in three colour variants, where the dial and bezel match in colours nicely. The colour palette consists of deep blue, grey, and deep green. 


All three variants come in 44mm case size, and for the first time use a polished ceramic unidirectional bezel. This is the first time for the brand in general where a high gloss surface has been used for a bezel. Another first for the brand is the dial colours. Featuring a polished finish, the dial colours themselves have a gradient finish, where the colour deepens from the centre outwards. 

The Panerai Submersible QuarantaQuattro eSteel™ comes witha water-resistance of 30 bar (300m). The timepiece comes with two straps upon purchase, with both being in the same colour as the dial of the watch. Sustainability on the Panerai Submersible QuarantaQuattro eSteel™ is not just limited to the case material. Both straps offered are sustainable products, with the first strap being made from recycled PET fabric and the second strap made from recycled rubber. The watches feature a brushed steel Safety Lock Crown protection device so that the crown doesn’t come undone during deep dives. On the protection device, there is an engraving of eSteel™, making the sustainable product known.

The dial is kept relatively simple, with large hour indices and hands filled with Super-LumiNova for low visibility areas. There’s a simple date window at 3 o’clock accompanied by a constant seconds counter on the opposing side at 9 o’clock. 


The engine behind the Panerai Submersible QuarantaQuattro eSteel™ is the automatic mechanical P.900 calibre movement. At just 4.2mm thick, the movement operates at 4Hz (28, 800VpH). The P.900 calibre movement also comes with a hefty power reserve of approximately three days.

A watch featuring a few firsts for the brand, the Panerai Submersible QuarantaQuattro eSteel™ certainly brings something different to the table. The Submersible collection just received a fresh update with beautiful coloured dials and is now a more environmentally friendly sustainable product. The brand is doing its part to be more environmentally friendly with the watches they create, with the Panerai Submersible QuarantaQuattro eSteel™ being a big step in the right direction.
