ساعت جیبی همانگونه که از نام آن پیداست بمنظور قرار گرفتن در جیب افراد ساخته شده‌است که معمولاً توسط زنجیری به جهت جلوگیری از افتادن ساعت و استفاده مطمئن به لباس بسته می‌شوند. این نوع ساعت تا پیش از اختراع ساعت مچی، محبوب‌ترین ساعت از قرن ۱۶ میلادی تا پس از جنگ جهانی اول بودند از دورانی که ساعت‌های جیبی و جلیقه، جزئی از سبک پوشش مردان بودند زمان نسبتا زیادی گذشته و ساعت‌های مچی دیجیتالی و عقربه‌ای و حتی هوشمند باعث شده‌اند به عقیده‌ی اکثر افراد جایی برای این ساعت‌های دوست داشتنی باقی نماند. ساعت‌های دوست داشتنی که گاهی برخی از افراد عکس همسر یا مادرشان را درون در آن میچسباندند تا هرگاه در ساعتشان را باز می‌کردند با چهره‌ی خندان عزیزشان رو به رو شوند They were the most common type of watch from their development in the 16th century until wristwatches became popular after World War I during which a transitional design, trench watches, were used by the military. Pocket watches generally have an attached chain to allow them to be secured to a waistcoat, lapel, or belt loop, and to prevent them from being dropped. Watches were also mounted on a short leather strap or fob, when a long chain would have been cumbersome or likely to catch on things. This fob could also provide a protective flap over their face and crystal. Women's watches were normally of this form, with a watch fob that was more decorative than protective. Chains were frequently decorated with a silver or enamel pendant, often carrying the arms of some club or society, which by association also became known as a fob. Ostensibly practical gadgets such as a watch winding key, vesta case, or a cigar cutter also appeared on watch chains, although usually in an overly decorated style. Also common are fasteners designed to be put through a buttonhole and worn in a jacket or waistcoat, this sort being frequently associated with and named after train conductors.
