The so-called one-piece long watch straps have a big family "NATO watch straps", which makes them highly adjustable to any wrist size. They are usually made of nylon or textile and hence suitable for summer wear. On the image below you can see some of the common types of watch bands made from this family:
(D1) RAF Nato strap with one big keeper
(D2) Perlon watch strap is plaited. Both (D1) & (D2) one piece long straps' detachable ladder lock buckle can simply be inserted anywhere through the strap rather than through pre-cut holes, with loose (or 'floating') keeper on them.
(D3) NATO watch strap / Nato Bond strap with slim and lightweight Sewn-in buckle and keepers
(D4) Zulu strap with thicker and heavier Sewn-in buckle and keepers
(D5) One piece watch bands are the bracelets whose length adjustment is limited to the buckle micro holes. They usually have the higher longevity than the former and may be more practical (image below).
