At first glance it’s not easy to differentiate E3 from E4 45mm. This side by side pictures are helpful:

Thanks! 👍

Yes, of course Gen2 Modular is also my favourite. Being the only Modular (with available mechanical modules) and the only Swiss Made generation makes it unique, together with a very personal and distinctive design.

It’s also the generation with more available straps and bracelets, with more Special and Limited Editions, with more customization options (many different bezels, four different types of lugs)…

so TAG Heuer really invested in this generation, the last one under JC Biver management


Totally agree 👍

Yes, I forgot the mechanical module for E2 Modular 41. Post is edited to include it, thanks! 👍
