The Spitfire is modelled in miniature here, wings out and tail low, worked in 9ct gold. The detail is small but clear: the elliptical wing, the raised cockpit, the propeller boss at the nose. The finish is bright, so the aircraft catches the light as it turns.
A tie tac fixes through the tie and holds it against the shirt, so the shape sits flat rather than swinging from the edge of the blade. Worn a little below the collar, it reads as a point of gold until someone is close enough to see what it is. It suits a plain tie best, where there is no pattern competing with the outline.
It arrives in a presentation gift box, ready to hand over on the day.
