Hi guys

I would like to purchase the above watch however I was wondering could you help me out with a few questions please?

I'm thinking of purchasing the turquoise version however it appears to come with the black strap as standard. I would like to know can I change the colour of the strap to the turquoise isoframe included in the price or will it have to be purchased as an extra?

Secondly as I'm new to the Rubber/Isoframe strap options can you explain or advise which option I should go for in terms of lug width from the drop down menu when attempting to purchase the isoframe strap?

Thanks for your help In advance
