Rotary Expander Watch - LB00764/29

My late husband bought me this Rotary 007/64 watch for my 60th birthday. I have loved wearing it since but recently I have lost two links from the expanding bracelet.
I wear my watch on the underside of my wrist as I used to be a teacher and needed to be able to check the time whilst looking at a students work, without making it obvious!
I have recently lost two of the links in the bracelet which gives it a strange appearance.
I am now nearly 86 and would like to continue wearing it but, at weekend, my daughter took me to Cambridge where we checked every watch shop to try to purchase a new expanding bracelet but did not find anyone who could supply me with a replacement
Are you able to bring it back to it's former glory.
