OOOH, so when it's time to upgrade, just buy a mechanical module? Oh, it'd be cool if tagheuer updated the watch (e.g refreshed the 41 and 45mm models in the future) and let us buy ONLY the module for cheaper!
Which brings me to my next question: I've seen ppl here say that the module itself is about $400 and the rest of the cost is actually the retail price of the strap, lugs etc. I've tried to look around a bit, but - has anyone compared the mechanical modules to equivalent watches by themselves in terms of price? I don't know much about watches and tagheuer has a lot of watches so I'm confused, but for eg: a basic rubber with titanium case 45mm costs $1550 then the Calibre 5 module is about $1650, bringing the total to $3200. I'm curious to know how that cost compares to an equivalent mechanical watch, with similar materials (so silicone/rubber strap). I've tried to look around but I have no idea what an "equivalent watch" for the calibre 5 module would be.
Although, IIRc there is a calibre 16 with rubber strap that costs $4200 by itself, which is comparable to the cost of CM45 + Calibre16 module.
