Another option is to purchase an adaptor and then purchase whichever 20mm watch band you wish.

and then you could get quick release watch bands like so - https://www.amazon.com/gp/product/B01N0XU2T4/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

I went that route for my wife and I's watches. The fit on the adaptor for mine was perfect on hers was slightly loose but nothing that bothered her. The adaptors we received were made of metal (as the description mentioned) and I got one in black she preferred the silver look to match her watch.
