As it happens, I was in my local AD yesterday getting a strap change on a JLC and spent time with the Lange offerings they have there. I had on the Richard Lange in RG and the 40.5mm feels just about perfect on my wrist. The warmth of the RG mixed with the balance of the sweeping seconds makes this a winner in my eyes. Plus the movement is just gorgeous with the indirect drive attachment for the seconds hand.
Also tried on the new WG Lange 1 TZ which was a surprise as it has just landed in stock. The lume on the hands brings an element of sport to this beauty.
No doubt in my mind now that my first Lange will be the RL, the question is whether in RG or PT. I've yet to see the PT in the metal.
Thank you for posting your pictures, I think we share the same appreciation.
