Picked up a Omega Aqua Terra 41mm earlier this year - with the date at the 6'oclock window - it comes with a Nato strap and looking to replace it with a black leather strap.
Had a look at my local dealer and they advertise the Omega branded straps at £200!!! which sounds a little expensive.
I've had a look on amazon/etsy/ebay and they have different sizes e.g 21mm strap, 20mm strap, 19mm strap.
Main questions are:
What size should I pick up for a 41mm?
Any recommendations for what company to use, or website etc to purchase from?
