I purchased a blue elastic strap to replace the metal bracelet on my Baltic chronograph and it make me fall in love with the watch all over again. It is by far the most comfortable strap I own and very handsome as well. One they come out with an 18 mm I will buy them for all my other watches
The material is great and indeed very stretchy. I think i somewhat made a mistake and ordered 130mm so first few wears have left my wrist with mark, but after i stretched it a bit, it is much more comfortable now. As per the suggestion for in between sizes, might be better with sizing up. Looking forward to more colors/variations in future.
