Thank you and it complements Mark's review on this model. Just one small point which might be deemed irrelevant but the 5130 is 39.5mm (instead of 39mm as stated in your review). I personally think that the enameled pieces and the 5575G apart, the 5230 is the best looking world timer as compared to the 5110 and 5130. It is quite interesting that the sought after 5575G is 39.8mm, the largest of the world timers. With Patek sometimes, it is not so much the size but the curvature of the lugs and what lovely lugs on the 5575 and 5230!
Best wishes,
