An injection device comprising - a housing (10; 410), - a dose indicator (90; 480) positioned within and axially constrained to the housing (10; 410) and rotatable with respect to the housing (10; 410) during dose setting and during dose dispensing, wherein the dose indicator (90; 480) provides a number display; - a gauge element (80; 490), which is at least partly interposed between the housing (10; 410) and the dose indicator (90; 480), wherein the gauge element (80; 490) is guided within the housing (10; 410) in an axially displaceable but rotationally fixed manner, and wherein the gauge element (80; 490) is in threaded engagement with the dose indicator (90; 480) such that rotation of the dose indicator (90; 480) causes an axial displacement of the gauge element (80; 490), wherein a contrast element having a first marking is provided, wherein the contrast element is axially constrained to the housing, wherein at least a region of the gauge element (80; 490) is provided with a second marking, wherein the region of the gauge element (80; 490) having the second marking is interposed between the housing (10; 410) and the contrast element, wherein the gauge element (80; 490) screens or uncovers the contrast element as the gauge element (80; 490) travels axially within the housing, wherein it depends on an axial position of the gauge element (80; 490) whether either only the first marking is visible or only the second marking is visible or both the first marking and the second marking are visible through a first window or aperture in the housing (10; 410), such that an analogue optical dose set and dispense feedback feature is provided in addition to the number display, wherein the gauge element (80; 490) does not protrude out of the housing (10; 410) during dose setting and during dose dispensing. - a housing (10; 410), - a dose indicator (90; 480) positioned within and axially constrained to the housing (10; 410) and rotatable with respect to the housing (10; 410) during dose setting and during dose dispensing, wherein the dose indicator (90; 480) provides a number display; - a gauge element (80; 490), which is at least partly interposed between the housing (10; 410) and the dose indicator (90; 480), wherein the gauge element (80; 490) is guided within the housing (10; 410) in an axially displaceable but rotationally fixed manner, and wherein the gauge element (80; 490) is in threaded engagement with the dose indicator (90; 480) such that rotation of the dose indicator (90; 480) causes an axial displacement of the gauge element (80; 490), wherein at least a region of the gauge element (80; 490) is provided with a second marking, wherein the region of the gauge element (80; 490) having the second marking is interposed between the housing (10; 410) and the contrast element, wherein the gauge element (80; 490) screens or uncovers the contrast element as the gauge element (80; 490) travels axially within the housing, wherein it depends on an axial position of the gauge element (80; 490) whether either only the first marking is visible or only the second marking is visible or both the first marking and the second marking are visible through a first window or aperture in the housing (10; 410), such that an analogue optical dose set and dispense feedback feature is provided in addition to the number display, wherein the gauge element (80; 490) does not protrude out of the housing (10; 410) during dose setting and during dose dispensing.
