Seiko Prospex watch reissue 1965 Heritage Diver's Special Edition 40mm SPB455J1

Special edition for the 100th anniversary of the firm

This Seiko Prospex watch is an evolutionary improvement of the original Seiko Heritage Divers from 1965, which was already modified in 2020 but now adapts to the new times with several improved features.

Among the changes introduced in this model is the more compact box. It is made of 46.4mm stainless steel with a thickness of 13mm. That is, this model is smaller than the previous version in terms of space between handles, width, thickness and glass. The case back is screwed, as is the crown.

The crystal is curved sapphire with anti-reflective coating on the inner surface of the crystal. The dial is black with Lumibrite treatment on the hands, indexes and bezel. The indexes and hands are gold.

The bezel is unidirectional rotating in black with indexes and numbering also in gold.

Another of the most significant aspects of this watch is that it extends its water resistance to 300m (30 ATM). All thanks to the precision of the case back.

The bracelet is made of stainless steel with a secure locking folding clasp and extender. The links are slightly shorter than the previous model. They now have 8.0mm, which provides more fit on the wrist.

Includes extra strap made entirely from recycled plastic bottles.

The calendar is positioned between 3 and 4 o'clock.

The Caliber 6R55 automatic movement with manual winding capability provides a power reserve of 72 hours. It has an accuracy of +25 to -15 seconds per day and is made of 24 jewels.

Among the functions offered by this watch are the hours, minutes and seconds and the seconds hand.
