When you purchase from H.S.Johnson we will resize your watch bracelet free of charge before dispatch, all you need to do is measure around your wrist where you ideally want the watch to sit and at the tightness you prefer, best to add around 5mm or 1/4 inch to the measurement to avoid pinching, then just email your size required to email@example.com with your order number straight after purchase.
Things to consider........
If you need extra links to make fit there may be a delay in dispatch if these need to be ordered in, they are often free of charge to order but some brands will apply an extra charge for this.
We always include any removed links with your watch purchase.
You can of course get it adjusted locally to make it an exact fit if you are unsure but this will have a cost you would have to cover.
